->''"Rarity is excited to welcome her new apprentice, Charity, to Ponyville. Rarity is sure that the two of them will become best friends, bonding over their love of fashion and glamour.

The fourth [[note]]excluding an ''[[WesternAnimation/MyLittlePonyEquestriaGirls Equestria Girls]]'' {{novelization}} [[/note]] officially licensed ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' chapter book of a series of books by G. M. Berrow, and part of the overall Franchise/MyLittlePonyGeneration4 universe. Just like the previous three books, this also takes place some time after season three[[note]]With one line in particular suggesting that it takes place in the middle of season 4.[[/note]] Rarity is selected to be a part of a mentoring program that would allow up-and-coming fashion designers to learn from the pros. She soon meets her apprentice Charity Sweetmint, who turns out to be a big fan of Rarity's work and the two hit it off fairly well. However, things become difficult when Charity takes her idolization of Rarity too far.

She is not named (Rarity can't seem to remember it) and she is unable to talk properly (she has Rarity's letter in her mouth while she's trying to talk), but it's pretty clear she's supposed to be Derpy.
