List of allusions

The following is a list of allusions to My Little Pony, works of fiction, people, places, events, and other cultural touchstones in the series My Little Pony Friendship is Magic.

The allusions, references, similarities, homages, and other items on this list should be specific, detailed, unique, or identifying. Avoid adding incidental, broad, general, or tangential similarities.

Character names and design

 * All the designs of the leading characters, Twilight Sparkle, Applejack, Rainbow Dash, Rarity, Fluttershy, Pinkie Pie, and Spike are inspired by G1 characters: Twilight, Applejack, Firefly, Sparkler, Posey, Surprise, and Spike, respectively.
 * Applejack's name and the derisive nickname Appletini that Spike gives her in Bridle Gossip are both names of alcoholic beverages.
 * Big Macintosh, Granny Smith, Braeburn, and several of the Apple family members' names are of apple cultivars. Still, other members' names are of culinary dishes made with apples.
 * Big Macintosh's design is inspired by the G1 Big Brother Ponies.
 * The royal guards wear crested helmets reminiscent of Roman galea.
 * Snips and Snails, two colts, are a reference to the nursery rhyme "What Are Little Boys Made Of?".

Other names, titles, and design

 * Canterlot is a portmanteau of "canter", a three-beat horse gait, and Camelot from Arthurian legends.
 * Cloudsdale's suffix, "dale", is an old word for a valley or open river valley, but the name is also a play on the Clydesdale breed of horse. The city's buildings and general design take clues from Greek culture, which is appropriate as the myth of Pegasus originated from Greek mythology.
 * The hot air balloon that is featured in the opening sequence and other episodes was requested to be incorporated into the show by Hasbro's toy division.
 * The Wonderbolts appear to be based on the U.S. Navy's flight demonstration team, the Blue Angels. They resemble the Blue Angels in uniform color–blue and yellow–and the "flying bolt" logo, evocative of the "flying shield" portion of the Blue Angels logo.

Mythology

 * The show features dragons, unicorns, and Pegasi in multiple episodes, and several other mythological creatures detailed in individual episode sections below.
 * The realm of Tartarus is named after the Greek mythological Tartarus realm of the same name.

Audio

 * Granny Smith's voice clips from Friendship is Magic, part 1 are re-used to make every speaking appearance she has throughout season 1, excluding Griffon the Brush Off.

 * Pinkie Pie's one-pony band fanfare to rid Ponyville of the Parasprites in Swarm of the Century, is re-used later as the party music in Pinkie's flashback scene in The Cutie Mark Chronicles.

 * The line 'Holy Guacamole!' is one of the very few instances in which a single clip of audio is re-used in the same episode. It is spoken by Spike during the middle and end sections of Feeling Pinkie Keen and was originally intended to be his catchphrase before being dropped for undisclosed reasons.

Suited For Success

 * Pinkie Pie's line "I love something. Something's my favorite." echoes the line "I love smiling. Smiling's my favorite" from the film Elf.
 * When Rarity considers exile she says, "Where would I go? And what would I pack?" in a fashion that echoes a line by Scarlett O'Hara in the 1939 classic film Gone With The Wind, "Where shall I go? What shall I do?"
 * The sequence where Rarity has locked herself in her room and says "I vant to be alone" with an Eastern European accent echoes the famous phrase associated with actress Greta Garbo.
 * This line may also be a reference to the G1 episode "Sonambula", when the similarly accented Heartthrob declares that she "vants to be alone".
 * Hoity Toity bears a strong resemblance to Karl Lagerfeld, head designer and creative director for the Chanel fashion house.
 * The headdress for Rainbow Dash's "perfect dress" strongly resembles the shape of the helmet of the comic book character The Rocketeer.
 * The musical opening of Rarity's second fashion show has a short sound-alike segment for Also sprach Zarathustra, popularized in the film 2001: A Space Odyssey.
 * The music that accompanies Fluttershy is a sound-alike of Debussy's Prélude à l'après-midi d'un faune.

Feeling Pinkie Keen

 * The episode was developed from the old wives tale of achy joints predicting the weather and the Raining Animals Phenomena, which was expanded into Pinkie Pie's Pinkie Sense.
 * Fluttershy's fear prevents her from flying, as it does in Dragonshy. However when she has to jump to safety, she uses what she learned from Dragonshy and works up her nerve by repeating a line from Pinkie Pie's song.
 * The episode features a Hydra, a mythological creature of Greek legend.

Sonic Rainboom

 * Rarity's hubris, leading to the loss of her wings to the sun, echoes the story of Icarus from Greek mythology.

The Show Stoppers

 * Scootaloo's failure to find a decent rhyme, frustrated "NEVER, NEVER!", and piano head-desking are lifted straight from Don Music in Sesame Street.

A Dog and Pony Show

 * The phrase "a dog and pony show" originated in 19th century America as a term for small traveling circuses that toured through rural areas. The modern usage refers to an over-staged performance. Typically, the term is used to connote disdain, jocular lack of appreciation, or distrust of the message being presented or the efforts undertaken to present it.
 * The episode's plot is reminiscent of the O. Henry story The Ransom of Red Chief, in which a young boy's antics drive his kidnappers so crazy that they end up paying his family to take him back.

 * The Diamond Dogs take their name from David Bowie's famous concept album and its titular song, Diamond Dogs.
 * In Spike's fantasy, the Diamond Dogs attack with the characteristic slow motion leap and 'bionic' sound effect from The Six Million Dollar Man.

 * Fluttershy calling Spike "Huffy the Magic Dragon" is a reference to the 1963 folk song Puff, the Magic Dragon sung by Peter, Paul and Mary.
 * Spike plays the piano in this episode. His predecessor in the My Little Pony movie Escape from Midnight Castle has a similar scene where he plays the piano.
 * The battle scene at Appleloosa when a buffalo strikes a haystack with an anvil behind it is the same gag from the 1953 Bugs Bunny cartoon "A Bully for Bugs," in which a bull hits an anvil behind Bugs' toreador cape.
 * The name of the episode references an old idiom "over a barrel". To have someone "over a barrel", is to have them at your mercy.

A Bird in the Hoof

The Cutie Mark Chronicles

 * "Princess Celestia's School for Gifted Unicorns" is similarly named to X-Men's "Xavier's School for Gifted Youngsters".
 * Applejack travels to Manehattan, a play on Manhattan, a borough of New York City. New York City is also known as the Big Apple.
 * The Orange family's name is a reference to the phrase "apples and oranges", a comparison of two very different things, much like how Applejack does not appreciate the Orange family's very different lifestyle.

Owl's Well That Ends Well

 * When Spike falls asleep in the punch bowl, Pinkie Pie says "And now the punch has been... Spiked!", a play on "spiking the punch", which means adding alcohol to the punch.

 * The magical apple carriage, the mice being turned into horses, and Rarity accidentally leaving her glass slipper are elements from Cinderella.
 * Hayseed maintaining the garden says he likes to "whistle while [he] works," a reference to Disney's Snow White and the Seven Dwarfs. The whistle is the same tune Snow White sings into the well.
 * The golden apple tree Spike mentions at the beginning of the episode that he wants to show Applejack could be from a number of fairy tales, The Golden Bird by The Brothers Grimm being an example.
 * Fluttershy's plan to catch the animals, complete with maniacal laughter, somewhat echoes the Wicked Witch of the West from the 1939 film adaptation of The Wizard of Oz.

 * The song sung before the gala is a sound-alike of Ever After from the fairy-tale-themed musical Into the Woods.
 * Pinkie Pie`s Pony Pokey is a version of the hokey cokey dance.

 * The "chocolate rain" used by Discord is likely a reference to Chocolate Rain by Tay Zonday.

The Return of Harmony Part 2

 * According to director Jayson Thiessen, one of the storyboard artists decided to board the award ceremony sequence at the end of the episode as a shot-for-shot equivalent of Star Wars Episode IV: A New Hope, though parts of the sequence were ultimately cut to shorten the episode.

Lesson Zero

 * The scene where Twilight starts talking to her reflection in a puddle is similar to the scene with Gollum from The Lord of the Rings: The Two Towers.

Luna Eclipsed

 * The episode title could be a pun on "lunar eclipse", which is when the sun, moon, and Earth are directly in line with one another.

Sisterhooves Social

The Cutie Pox

 * At the bowling alley, four of the male ponies look similar to characters from the film The Big Lebowski, which features the theme of bowling.
 * A 'ponified' version of the painting American Gothic hangs on the wall in the living room of the Apple family's house.
 * One of the cutie marks Apple Bloom receives is a red shoe which causes her to dance uncontrollably, like the main character in the Hans Christian Andersen fairy tale The Red Shoes.
 * The statue Apple Bloom constructs is Venus Anadyomene, a common theme in art in antiquity and the renaissance.
 * Applejack asks Zecora, "Was your zebra sense a-tinglin'?", which is a reference to Spider-Man's spider-sense ability.

The Mysterious Mare Do Well

 * The episode's lead storyboard artist, Sabrina Alberghetti, commented on how the crew incorporated "one [superhero] cliché after another" in a "fun tongue-in-cheek kind of way." Among them:
 * Rainbow Dash's catchphrase, "never fear, your friendly neighborhood Rainbow Dash is here!" is a play on both "your friendly neighborhood Spider-Man", and "There’s no need to fear, Underdog is here!"
 * The Mysterious Mare Do Well shares the same purple-and-black color scheme and wide-brim hat and black ribbon as Darkwing Duck. Alberghetti had worked on Darkwing Duck comics before, however she did not design the character.
 * The fanfare, accompanying music, and rally posters of the Mare Do Well strongly resemble the same from Batman: The Animated Series.
 * The musical score as the cart rolls uncontrollably downhill mimics the score of the film Speed.
 * The name "Mare Do Well" is an ironic reference to the term ne'er-do-well, a person who does no good.

Sweet and Elite

 * Among other places Rarity visits in the montage is an art exhibit, where the central painting on the wall combines elements of Salvador Dalí's paintings, particularly The Persistence of Memory. The painting to the left resembles Pablo Picasso's signature style of Cubism. The painting to the right is an abstract style akin to the works of Kandinsky. The show's director, Jayson Thiessen, had hinted about Salvador Dali and avant-garde in an interview in September 2011, long before the episode's initial broadcast.
 * The bags that Rarity uses to carry her shopping in before she runs into Fancypants for the first time have two horseshoes arranged to imitate the Chanel fashion house branding.

Secret of My Excess

 * One of the working titles of the episode, "Attack of the 50 Foot Dragon", is a play on the movie title Attack of the 50 Foot Woman, and it hints to the episode's "giant monster rampaging through a city" theme that popularized by the 1954 film Godzilla.
 * The siren that sounds when Spike begins rampaging through the town is similar in design and sound to Civil Defense sirens of the 1950s and '60s.
 * The kidnapping of Rarity and subsequent aerial assault on Spike draws parallels with the classic 1933 film King Kong.

Family Appreciation Day

 * The Smith family's appearance highly resembles the Western American pioneers of the late 1800s. Additionally, the wagon they hauled resembled the type of covered wagons used during the period.

Baby Cakes

 * The brief screeching violins that play when Pinkie Pie finds Pound Cake on the ceiling echo the musical piece The Murder, made famous by the film Psycho. The scene in general is modeled after horror films, with an unidentified silhouette crawling in the shadows.
 * The music that plays when Pinkie Pie urges the Cakes to pick her as babysitter is based on Aquarela do Brasil, a Brazilian samba standard from the 1930s.
 * Pinkie's instructions for using the crib mirror a line from The Simpsons episode The Last Temptation of Homer.

The Last Roundup

 * The scene where Pinkie Pie and Fluttershy work at a conveyor belt and can't handle the pace is a homage to the television series I Love Lucy. The scene replicates one from the I Love Lucy episode "Job Switching", where Lucy and Ethel wear mushroom-like hats and work on a production line wrapping candies. They can't handle the pace and stuff the unhandled chocolates into their hats and mouths.
 * Rainbow Dash mentions Calamity Mane and Wild Bull Hickok, whose names are based off two prominent Wild West figures.
 * Dodge Junction is a namesake of Dodge City, a famous locale for Western films.
 * Applejack's quote "I need to get out of dodge," is a reference to a quote from the TV show Gunsmoke, in which villains were told to "Get the hell out of Dodge."

The Super Speedy Cider Squeezy 6000

 * The musical number The Flim Flam Brothers shares many similarities with the number "Ya Got Trouble" from The Music Man. Specifically, the identical rhyming styles, staccatos, and theme of smooth talkers trying to win over a small town. Also, mid-song, the ponies chant "cider, cider, cider" in the same manner that the people of River City chanted "trouble, trouble, trouble" in the Music Man number.
 * The scene where one of the Flim Flam brothers asks Granny Smith if she's "chicken" bears similarities in staging and dialog to a scene from the film Back to the Future Part II.
 * The competition between the Apple family and the machine is a homage to the legend of John Henry.

Read It and Weep

 * The musical cue that plays when Rainbow Dash looks at the book and starts reading it is very similar to the one that plays in a similar scene in the film The NeverEnding Story.
 * The title "Read It and Weep" is a reference to a saying of the same name.
 * The quote of Pinkie Pie saying "Did the crash somehow give her super-duper spider powers?" and the doctor saying "No, nor it gave her the amazing healing powers", resembles to Marvel Comics references; the "spider powers" resembles Spider-Man, and "healing powers" resembles Wolverine from the X-Men.

 * The Ahuitzotl is a creature of Aztec mythology.
 * Ahuitzotl petting his white cat at the end of the Daring Do story is a cinematic element made famous by the character Ernst Stavro Blofeld of the James Bond series.
 * There are several allusions to the Indiana Jones franchise:
 * The harp plucking that plays when Daring Do first enters the temple bears a strong resemblance to the music that plays in the opening of Raiders of the Lost Ark when Indiana Jones casually brushes spiders off of his back.
 * The sunlight shining into the chamber is a reference to the map room scene from Raiders of the Lost Ark, where the sunlight shines on a crystal at the center of the room.
 * The way Daring Do makes her way to the Sapphire Stone's pedestal mirrors a scene from Indiana Jones and the Last Crusade where the titular hero navigates a trap floor by only stepping on the correct tiles.
 * The scene where Daring Do retrieves the Sapphire Stone mirrors a scene from Raiders of the Lost Ark in which Indiana Jones retrieves a statue of an idol from pedestal.

Hearts and Hooves Day

 * The holiday featured in the episode shares many similarities with Valentine's Day and was originally aired a few days before the holiday. It features couples spending time together and the exchange of greeting cards.
 * The story behind the Love Poison is based on the Arthurian legend, "Tristan and Isolde."

A Friend in Deed

 * The episode's title is part of the phrase "a friend in need is a friend indeed".
 * "Cranky Doodle Donkey" has the same meter as Yankee Doodle Dandy, a pejorative song sung by the British to mock the American revolutionaries. Pinkie sings a song about him to the tune of Yankee Doodle Dandy.
 * The song she sings at the end is based on the version of the song from the film of the same name
 * Pinkie's line "Ooh, what does this bauble do?" is nearly homophonic to "Ooh, what does this button do?", the catchphrase of the character Dee Dee from the cartoon Dexter's Laboratory.

Putting Your Hoof Down

 * Fluttershy paraphrases the famous line from the 1939 film Gone with the Wind, "As God is my witness, I'll never be hungry again!", much like Rarity in Sisterhooves Social. Though in these cases, "God" is replaced by "Celestia".
 * The name "Putting Your Hoof Down" is a reference to the saying, "Putting your foot down," which refers to when someone stops dealing with an exasperating situation.
 * In a scene featuring the character Iron Will in his workshop for assertiveness, a background music clip borrows from the primary motif of Eye of the Tiger by Survivor.
 * Iron Will's presentation takes place in the center of a hedge-maze, a reference to the Labyrinth of Greek mythology, which held the Minotaur, a half-man, half-bull creature, at its center.
 * Iron Will's character appears to be inspired by actor Lawrence Tureaud, aka Mr. T, and other characters of the 'Macho Man' archetype. The inspiration extends even further to the former using a variation of the latter's famous 'I pity the fool' catchphrase.
 * Pinkie Pie's negotiation trick with the Tomato Stallholder and Iron Will is derived from a similar trick used in several Looney Tunes animated shorts, including 1946's Baseball Bugs and 1951's Rabbit Fire.
 * Some of Iron Will's gestures in theatrics resemble those of professional wrestlers. Most notably when Iron Will states that he wants to hear the audience, he makes a hand gesture to his ear similar to that of one of wrestling legend, Hulk Hogan's signature taunts.
 * The episode incorporates a sound-alike of the theme "The Lonely Man" from the CBS television series The Incredible Hulk.

It's About Time

 * This episode borrows two elements from Greek mythology:
 * The Cerberus is the three-headed canine that protects the gateway to the Underworld, the realm of the dead.
 * Tartarus, the area that the Cerberus in this episode guards, is one of the darker and deeper depths of the Underworld where the wicked are said to depart to after death.
 * When Rainbow Dash reports to Twilight about the safety of Ponyville, she mentions "Fillydelphia" and "Las Pegasus", a play on the cities of Philadelphia and Los Angeles or Las Vegas, respectively. Later, she also mentions "Baltimare", a play on the city of Baltimore.
 * The background music that plays during the encounter between Twilight and her future self is homophonic to I am the Doctor, the main theme of the Doctor Who series.

Dragon Quest

 * The episode shares its name with a popular RPG series.
 * The episode's plot is similar to an episode from the 1980s series My Little Pony, "Spike's Search" where Spike goes on a quest to learn to be a dragon and gets involved with a group of dragons who turn out to be thieves and bullies.
 * The game "King of the Hoard" the teenage dragons play appears to be the same as the children's game "King of the Hill."
 * The soundtrack during Spike's encounter with the teenage dragons features a sound-alike of wrestler "Stone Cold" Steve Austin's arena theme.

Hurricane Fluttershy

 * In the opening scene, Fluttershy tries to avoid going to the Pegasus meeting by disguising herself as a tree. This is likely a reference to her famous line from Over a Barrel, "I'd like to be a tree", which has become an in-joke in the fan community.

Ponyville Confidential

 * The title of the episode is an allusion to James Ellroy's 1990 novel L.A. Confidential, and the 1997 film adaptation. The episode's theme is a reference to its Hush Hush Magazine subplot.
 * A poster in Apple Bloom's room references the famous Internet meme Nyan Cat, but with Rainbow Dash rather than the iconic pop-tart cat
 * The headline "Snips and Snails and Bubblegum Fails" is an allusion to the nursery rhyme "What Are Little Boys Made Of?".
 * Rarity's line "Et tu, Gabby Gums?" is an allusion to the Latin phrase "Et tu, Brute?", traditionally attributed to Julius Caesar in the Shakespeare play of the same name, and is meant to express great shock against a trusted one's betrayal.
 * "Gabby Gums" line, "XOXO, Gabby Gums" is an allusion to the book and TV series "Gossip Girl", where the voice of the character always signs out with the phrase "XOXO, Gossip Girl."
 * One of Apple Bloom's baby photos is posed the same as the Coppertone girl ad.
 * Ponyville's newspaper, The Ponyville Express, is similar in name to the Pony Express, a famous mail service used in 1860 and 1861 in the United States.

MMMystery on the Friendship Express

 * The title of the episode references the 1934 crime novel Murder on the Orient Express, by Agatha Christie, as does the outcome of the case: nearly every passenger is responsible for one part of the "crime".
 * The hat Pinkie Pie wears and the bubble blowing pipe are references to the fictional detective, Sherlock Holmes. Twilight's hat also resembles that of John Watson, Sherlock's partner.
 * One of the books sticking out of Twilight's bag in her first appearance in the episode is the history book from the beginning of Friendship is Magic, Part 1.
 * When describing the cake Pinkie Pie references the song, "It's De-Lovely".
 * Mulia Mild's name and mannerisms are a reference to Julia Child.
 * Doughnut Joe appears to be a reference to Buddy Valestro from the TLC reality show, Cake Boss.
 * Pinkie's fantasies of the other bakers during her accusations are all allusions to multiple styles and genres of film.
 * First, the Gustave le Grand fantasy references black and white silent films, with the griffon playing the role of the dastardly villian often assoicated with films from the period.
 * Doughnut Joe's persona in Pinkie's fantasy, "Con Mane", is a reference to fictional secret agent, James Bond; addtionally, the opening to this fantasy parodies the franchises' iconic gun barrel sequence.
 * Finally, Pinkie's fantasy about Mulia destroying the cake is a reference to the Japanese film Yojimbo and similar ninja genre films.
 * At one point Pinkie Pie says she wants to know "who done it" before Twilight Sparkle pedantically corrects her grammar. The type of mystery being spoofed in this episode is known as a "Who Done It" as opposed to a "How Catch 'Em" or "Procedural."
 * The episode also references the 1943 film, I Dood It, starring Red Skelton.

A Canterlot Wedding - Part 1

 * The Canterlot wedding (and the advertisements and promotions for the episode), are all a nod to The Royal Wedding of 2011. Specifically, the characters' attires match that of the special guests.

A Canterlot Wedding - Part 2

 * The lyrics and motif of This Day Aria reference the Disney Movie The Little Mermaid when Ursula, under the guise of Vanessa, is singing in front of a mirror talking about how she will have control over Ariel.
 * The idea of the Changelings might be a referance to Skrulls of the Marvel Comics Secret Invasion. Both species are capable of shape shifting, and they use this natural ability to replace high ranking members of society (Heros in the comics) allowing them to infiltrate unnoticed. And both invasions were lead by their queen and ultimatly failed
 * At the end of the big fight scene, the six ponies explode out of a ring of changelings as a dramatic music cue plays. A scene almost exactly like this happens in the second Matrix movie, complete with explosion and music cue.
 * The fight between Princess Celestia and Queen Chrysalis is reminiscent of the climax of Harry Potter and the Goblet of Fire, where Harry and Lord Voldemort create a beam of magic between their wands and push "beads of light" back and forth along it. As in the episode, when the beads reach Voldemort's wand-tip the beam is broken and he is launched backwards in defeat.
