The level starts out with a Yoshi next to a sign. Yoshi must Ground Pound the dirt, and by smashing the pole all the way down, a cloud is revealed; if this cloud is hit by an egg, many Stars will pop out. The player must then go to the log; if the player destroys the next cloud, a Special Flower appears. Yoshi then comes across another pole (from which a red coin is revealed once ground-pounded completely). The player can destroy the clouds to reveal some Stars. After a while, the player can move on to the next area.

The player will emerge into a mud-filled area. The player will encounter a few monkeys, but will eventually find the Middle Ring. By going down a hill, the player will reach some poles, and will soon thereafter reach an Egg Block. A secret area containing multiple Donut Lifts, eggs, and Shy Guys carrying 1-Ups can be accessed here by swimming under the hill, where they will encounter some platforms; the one before the top one has a Spring Ball on it that leads to the secret area. Yet another cloud containing Stars follows the Egg Block, followed by a platform. The player will be able to move on to the next part of the level after a little while.

A red coin can be revealed by ground-pounding the pole. A swing of monkeys will appear trying to block the player's way; once the player passes this obstacle, the Yoshi can continue on its journey. After a few more obstacles, the end of the level will arrive.
