T.T.

T.T. is a living stopwatch who helped organize Time Trials. T.T. also allows the player to save ghost records on a Controller Pak. These ghosts, however, take up much space on the pak. If players beat his records on every track, he becomes a playable character. He is an unlockable character in both Diddy Kong Racing and Diddy Kong Racing DS.
