Dr. Hooves, also known as Dr. Whooves or Time Turner, is a background male Earth pony with an hourglass cutie mark. The character, unnamed in the show, was given the name Doctor Whooves by fans (as a reference to the British sci-fi drama Doctor Who, created by the BBC), which was adopted by the show's crew, and only later was the character explicitly given the name "Time Turner", chosen by Enterplay consultant Wendy Epstein, in Enterplay's 2012 set of trading cards and with the alternate punctuation "Time-Turner" on a 2012 IDW comic book cover; Gameloft's 2012 mobile game initially also gave him the name "Time Turner", but a 2013 update changed his in-game name to "Dr. Hooves", a name that has also been given to him in Mighty Fine's merchandise following the 2012 rejection of the original name "Doctor Whooves"; Funko has used "Dr. Whooves" for earlier merchandise and "Dr. Hooves" for later merchandise; Hasbro's toy sets also use "Dr. Hooves"; the episode Slice of Life simply calls the character "Doctor" and "Doc" respectively in the credits and in dialogue. Hasbro acknowledged the character's popularity in the Comic Con 2011 promotional poster, where he is explicitly posed in a way that his cutie mark is clearly visible. Dr. Hooves shares his design with Meadow Song and Lucky Clover.
