Flurry Heart

Princess Flurry Heart, also called Baby Flurry Heart, is an Alicorn foal and the newborn daughter of Princess Cadance and Shining Armor. She appears in the two-part season six premiere and the storybook Good Night, Baby Flurry Heart.

Development and design
Flurry Heart's name was first revealed on a German Hasbro Newsroom website on January 21, 2016.

She is one of few Alicorns depicted as babies, another example being Princess Skyla. Flurry Heart resembles Evening starlite in pony type and coat and mane colors and shares her wing design with Twilight Sparkle and alternate-timeline Pegasus Pinkie Pie. Unlike the body design used for most infant ponies in the series, such as Pound Cake and Pumpkin Cake, Baby Flurry Heart uses the body design previously used for Applejack's birth certificate in The One Where Pinkie Pie Knows.

On January 28, 2016, in response to a Twitter questioning of "the logic of cluttering things up with yet ANOTHER alicorn princess", Jim Miller said to "understand that I'm not the ONLY person making decisions. I have input but I win some and lose some." In an Equestria Daily interview, "Big Jim" stated, "I seem to recall that this actually came more from a storytelling opportunity rather than exclusively from Hasbro Brand, but they were excited about the possibility of a new alicorn."

Depiction in the series
Flurry Heart is first indirectly mentioned in the season five episode The One Where Pinkie Pie Knows, in which Princess Cadance and Shining Armor announce to Twilight Sparkle and her friends that they're having a baby.

Flurry Heart makes her on-screen debut in the season six premiere, her reveal being witnessed by the Mane Six, Princess Celestia, and Princess Luna. Unlike Twilight and Cadance, Flurry Heart is a natural-born Alicorn; Celestia remarks that "the birth of an Alicorn is something Equestria has never seen".

To commemorate Flurry Heart's birth, the Crystal Empire holds a ceremony called a "Crystalling", in which she is presented to the public, and the light and love within the Crystal Ponies makes the Crystal Heart stronger. However, her crying causes the Crystal Heart to shatter, potentially ushering in an eternal winter. During Twilight and her friends' efforts to restore the Heart, Flurry Heart makes things difficult for them by flying all over, teleporting all over the place, and zapping things with her magic.

With the help of Sunburst, the ponies carry out Flurry Heart's Crystalling and restore the Crystal Heart. It is only after the incident is over that Flurry Heart is given her name.

Magic
As a natural-born Alicorn, Flurry Heart possesses more powerful magic than newborn unicorns. A blast of magic created by her sneeze alone can blast through several ceilings, and her crying shatters the Crystal Heart into pieces. In addition, she can perform multiple consecutive teleportation spells. After the Crystalling ceremony, her magic is more stable and controlled.

Storybooks
Flurry Heart is featured in the storybook My Little Pony: Good Night, Baby Flurry Heart.
