In this sub-game, Kirby and King Dedede are in a fighting ring. Dedede will throw eggs and bombs at Kirby. Kirby must catch the eggs, but not the bombs. The player opens Kirby's mouth by pressing any button, and closes by releasing the button. Depending on how many eggs Kirby caught, he will score bonus points or even extra lives.
The object of this game is to skillfully eat the eggs that King Dedede tosses at Kirby! If Kirby eats a bomb, however, that's the end of Kirby and the bonus game! To open Kirby's mouth, press the A Button. To close Kirby's mouth, release the A Button. The number of extra lives rewarded will depend on how many eggs Kirby eats.”
