One of the various Derpy clones often seen in the background. Originally thought by some to be the Ditzy Doo mentioned in "Winter Wrap Up", she's also been called other names such as Flutter Doo, Kiki, and Bubbles.
There's been debate about what her name is/should be and whether or not she is related to Derpy. I personally consider Ditzy Doo to be Derpy's name.
