In this third game of the popular PC Engine/TurboGrafx-16 platforming series, King Drool steals the top half of the moon. Bonk, the caveman with the giant head, sets out to retrieve the lunar hemisphere. This game features candy power-ups that allow Bonk to shrink or grow.

In this run, Memory beats the game in record time using many mechanics and tricks that are similar to those in the first game. See the author's comments for details about the differences.
