The Lol

Derpy Hooves is a nickname given to a background pegasus character from the animated TV series My Little Pony: Friendship is Magic. The moniker comes from a stillshot in the pilot episode,wherein the character is seen wearing a googly-eyed expression similar to the DERP face. The show’s creator, Lauren Faust, later explained on her deviantART page[3] that the character’sgoogly-eyed face was an error by an animator. While the character remains officially nameless, Lauren Faust has also expressed that she may use Derpy’s design for another pony named “DitzyDoo”. Ditzy is mentioned in the episode “Winter Wrap Up” as a rather dim-witted pegasus pony, but she has not been introduced onscreen. Quote from Lauren Faust about Derpy Hooves:

FromFyre-Flye (Lauren Faust) – "Ha! I lurk around a bit and I noticed the Derpy phenomenon. As far as I know, her wall eyed moment was an accident -- or perhaps a layout artist entertaininghim/herself. Who knows? Background ponies have no name, and their butt symbols are picked at random, so she can be Derpy if everyone likes. A later episode references a less-than-intelligentlocal pegasus named “Ditzy Doo” so maybe she can be her if we ever need to show her. But I would not want to step on everyone’s Derpy love."

Faust later sold two sketches of charactersfrom the show’s “original pitch bible” to help with the relief effort in Japan that was going on at the time.[4] The user that won these two sketches, Metacritter, decided immediately to putone of the items back up for sale on ebay in an auction. Upon asking Lauren Faust for the blessing of this auction, he received this response in one of her deviantART journals[5]:From Fyre-Flye (Lauren Faust) – "
I’m offering 2 more drawings from the same batch of development sketches---- plus a brand new sketch. The first time I’ve ever drawn this character."
