Really Gnawty Rampage

Notes:
 * You can hit the boss before he lands on the ground. Be careful not to lose DK, though, as you'll need him near the end.
 * Running DK into the boss after his third cycle will cause him to miss his fourth. Immediately jump on him again with Diddy to finish him off. If you time it so that he is near a wall, the final jump will be a lot easier to land.
