Walkthrough: Shortly after the spot where the N is located. You'll come across an area where another stationary tire and a high platform can be found. Use the tire to bounce up to the platform. Then, pick the barrel to the right and carry it. Bring it down from the platform and move to the right. There will be a pit with two Slippas. Throw the barrel into the Slippas and quickly follow it until it smashes into the right wall of the pit. Viola, bonus room #7.
A purple-colored cave level where you can find a tire on a moving floating platform and bananas in the air. Bounce on the tire to get all the bananas. By the way, don't worry about falling, below is a pit, but there's a tire in there that could bounce you back to the top platform. The exit is to the very right of the room.
