Like Mushroom Heights, this course is an athletic course with many mushroom platforms; these include stationary platforms, expanding/shrinking ones, and seesaw mushrooms similar to the ones seen in an Acorn Plains course not seen in the final game. Yoshi makes an appearance in this course as well.

- Star Coin 1: Underneath a row of Brick Blocks. Yoshi's Flutter Jump is required to reach it.
- Star Coin 2: In the middle of a group of spinning coins. Lakitu's Cloud is required to reach it.
- Star Coin 3: Above a shrinking/expanding mushroom is a green Warp Pipe that leads to the area with the third Star Coin. The player needs either Yoshi's flutter jump or a Super Acorn to reach the pipe and the coin.
