At the end of Season 1, one of the show's animators said that Derpy would say some lines in Season 2. In the episode "The Last Roundup", which shows Applejack competing for the Equestria Rodeo, Derpy Hooves talked a few times. Rainbow Dash says Derpy's name and Derpy speaks with a young boy's voice. At first, people thought that her voice was done by Brian Drummond, but it was Tabitha St. Germain, who didn't know at first that Derpy was female. Parent groups complained that this was insensitive to people with disabilities, and Hasbro changed the episode by making the pony's voice more girly and making Rainbow Dash not say her name. Another pony character with neon colors in her hair, wearing sunglasses and using a DJ set in one episode, was given the stage name of "DJ P0N-3" in a poll with the other choices being "DJ Clip Clop", "Scratch", "Deadhor5" and "DJ Raverider". DJ P0N-3 was later in the Equestria Girls ad and has been a background character in some other episodes. Derpy and DJ-PON 3 eventually starred in the show's 100th episode, Slice of Life, which focused on the show's background characters as a tribute to the fans.
