Pimm

Pimm is the secondary antagonist in Barbie in the Nutcracker. He is a purple bat who spies on the Nutcracker and his companions for the Mouse King. Pimm's personality can be described as timid, obnoxious, obedient, and slightly temperamental. He also has a high voice and a British (cockney) accent. He was impliedly more or less nicer before the events of the movie, but was more or less corrupted by the Mouse King. This is implied when the Mouse King said, "Very good, Pimm! I do believe I'm starting to rub off on you!"
He is voiced by Peter Kelamis, who also voiced Randall Boggs in Disney Infinity.
