Charity Sweetmint first appears in The Curious Case of Charity and is assigned as Rarity's apprentice by the House of Outrageous and Opulent Fashion (H.O.O.F.) Summer Mentor Program. When she arrives in Ponyville, she fawns over her would-be mentor, being a big fan of her work. Rarity initially addresses her as Sweetmint, but she prefers to be addressed as Charity, claiming "Sweetmint" to be just a nickname. Pinkie Pie and Applejack note how similar Rarity and Charity's names sound, and Spike becomes instantly infatuated with Charity.
