In the Game

Jimmy Bumples destroys Squirt's scooter at the beginning of the game. After the user has won one race on a given track, they must win another race against Jimmy and one other character for that track to be "won". When this process is completed for all the main characters' tracks, Jimmy's track is unlocked, and the game is won if that track is beaten. He is the only racer who is not playable and who does not have his own powerup.

He also appears in the activity Casey's Soccer Field as an obstacle on later gameplay levels

He has a "sidekick" named Skid.
