It's easier, that's right. But - if you seen it (Season 5 Eposode 100) they (Hasbro / DHX) call her "Muffins". "Derpy Hooves" is already a Fandom Name for her - in fact, she first named "ditzy doo" (that's why "Dinky Doo" is in the Fandom her Foal). After the Derpygate (Season 2 Episode 14) Hasbro needs to rename her - 'cause America. That's why she acutally named "Muffins". ("Bubbles" or "Grey bubbly Mare" was the first Description for her).That's why i called all her Names - that nopony can be angry.
