Bubbler's Course is the second boss course of Diddy Kong Racing and its remake Diddy Kong Racing DS and is found in the Sherbet Island world. In this level the player must beat Bubbler the Octopus around a circular water course featuring spinning logs for obstacles. Bubbler himself also drops additional obstacles in the form of spikes (bubbles in the rematch). There are some minor changes to the track in the DS version of the game.
