Zipper

Zipper is a little fly character from the animated series Chip 'n Dale Rescue Rangers. A running gag in the series is that he is often mistaken for an alien whenever he gets big or switches bodies with a human. Zipper is voiced by both Corey Burton and Frank Welker, Burton does the speaking voice while Welker does the sound of Zipper's wings flapping. He was introduced with Monterey Jack in the five-part origin story, "To the Rescue".
