Every apperance and cameo that Derpy has in Season 3 of My Little Pony. Some of them arent completely visibly Derpy, but I counted them anyway since the amount of apperances is so short. He/she appears in: Too Many Pinkie Pies, Magic Duel, Games Ponies Play, and Magical Mystery Cure. My Little Pony belongs to Hasbro and these clips are only being used to show how awesome the creators of the show are in putting in our favorite pony.
