Pipsy the Mouse

Pipsy the Mouse is a playable character in Diddy Kong Racing and Diddy Kong Racing DS who helps Diddy Kong and friends kick Wizpig out of Timber Island. Pipsy has as much acceleration and handling as Tiptup and Drumstick's karts have. In the intro screen of Diddy Kong Racing, Pipsy is seen playing a steel drum.

It is unknown if Pipsy or any other Diddy Kong Racing character was going to appear in Donkey Kong Racing and Diddy Kong Pilot respectively as Taj was going to possibly be a playable in Donkey Kong Racing and as Krunch was going to be one in Diddy Kong Pilot.
