Hint: Defeating Sweet Tooth:
Collect as many Freeze Bombs and Remote Bombs as possible, then get on the tent.
Set a Remote Bomb and a Freeze Bomb down and wait until Sweet Tooth gets on the
tent. Freeze him, blow him up with remote bomb, then hit him with your special.
If you get caught in his special in the process, just press Up, Up, Down, Down
and you will usually break out of it.
