Jeff Letrotski

Jeff Letrotski or Richard (the) Hoovenheart, also known as Jeff Letroski or Jeff "The Dude" Letrotski, is a male Earth pony who appears in the episodes The Cutie Pox, Simple Ways, and Somepony to Watch Over Me, dressed differently in each. His names are not mentioned on the show, but they are used in Gameloft's mobile game.

Development and design
Jeff Letrotski is one of four ponies based on characters from The Big Lebowski: himself, based on and named after Jeff "The Dude" Lebowski, Walter, based on and named after Walter Sobchak, Jesús Pezuña, based on and named after Jesus Quintana, and another Earth pony stallion, based on Theodore Donald "Donny" Kerabatsos. Richard (the) Hoovenheart is named after Richard the Lionheart.

Meghan McCarthy stated on the homage to The Big Lebowski and easter eggs in the show, "Very rarely are those things written into the script, but then when it goes to Studio B and the board artists and Jayson Thiessen, supervising director, I think they have a lot of fun. They have to populate this world with these background ponies and they’re like 'oh, they’re at a bowling alley, eh?'" A fan's thought that the bowler stallions' inclusion "was just the animators amusing themselves, rather than a sop to the adult audience" has been agreed to by Jayson Thiessen. Tim Stuby "had nothing to do with Lebowski."

Season two
Jeff Letrotski appears alongside another Earth pony stallion and Walter at the beginning of The Cutie Pox.

Season four
Richard (the) Hoovenheart appears alongside a filly at the beginning of Simple Ways and, with his cutie mark visible, alongside another Earth pony stallion at the end of Somepony to Watch Over Me.

My Little Pony (mobile game)
In Gameloft's mobile game, two versions of him are playable characters, similarly to Daring Do / A. K. Yearling and DJ Pon-3. The version of him present since early previews has the names Jeff Letrotski and either Jeff Letroski (after an update) or Jeff "The Dude" Letrotski (before an update), a different cutie mark and tail style than in Somepony to Watch Over Me, part of the same outfit as in both The Cutie Pox and merchandise, and the description "This laid-back pony loves to bowl and lounge around. His bowling rival is the formidable pony Jesús Pezuña." The version of him present since March 25, 2014 has the name Richard (the) Hoovenheart, the same tail style as in Somepony to Watch Over Me, and the same outfit as in Simple Ways. Jesús Pezuña has the description "This highly competitive pony loves to bowl against his rival Jeff Letrotski… and does not like to lose."
