During the battle, Bubble Crab's room has a tide that goes up and down and he raises his claws when trying to jump over him if X never prepares for the battle. Bubble Crab will sidestep like crabs do in real life, walks with a bubble shield and then shoots Bubble Splashes at him. When he has a bubble shield on him, X has to use Spin Wheel to pop the shield. Bubble Crab will also fire mini versions of himself in bubbles. If X shoots them, they home in at him. When there's no tide, the mini versions of him will bounce and he repeats the process. Another strategy is to let Bubble Crab cancel his shield by using Spin Wheel against him to save time.
