Location: Bouncy Bonanza
Items: 36 Bananas
Walkthrough: Can be found visible along the way near the exit. You need to move the tire into the floating moving platform and bounce to reach it or simply use Winky's ultimate jump if you have him.
You'll begin inside a floating rotating barrel. Carefully wait for the barrel to move face up then fire. This should launch your heroes into a pile of tires high above the cave. You can collect 36 bananas overall if you swipe every banana in this cave.
