Instructions
Locate the cake and press the "B" button to capture it with your stream. Move the cake into the oven to bring the chef out of hiding.
Press "Down" on the D-Pad to equip the Blast Stream and shoot the chef when he emerges. Dodge the utensils he throws at you while doing as much damage as you can. Eventually, the chef will retreat back into the oven.
Blast the pans that come your way and the chef will come back out. Monitor his energy level and continue blasting him until he is weak enough to capture.
Press the "Z" button to throw a trap beneath the chef. Once the ghost is safely inside, walk over to the trap and pick it up with the "A" button.
