Level Layout
In this level, Yoshi starts out going straight until Yoshi runs into a Winged Cloud. Yoshi must hit the Winged Cloud with one of his eggs to create a staircase for him to climb. Up on this platform, Yoshi can find another platform he can jump to to get three Red Coins. Afterwards, Yoshi must land on a pipe and must find another Red Coin. In the pipe, Yoshi can use Baby Mario's dash ability to collect a bunch of coins.

After collecting the coins, Yoshi must leave the cave and hit the Expansion Block to jump up onto a ledge. From the ledge, Yoshi runs into another Winged Cloud. Yoshi must hit it with an egg to reveal five stars. Afterwards, he jumps back to find a Paddle Wheel with some coins on it, some that are Red Coins. Yoshi must jump off the Paddle Wheel to jump up onto a ledge. Here, Yoshi can find some more coins with a Red Coin mixed in. Yoshi must continue to find an Crazee Dayzees and a Winged Cloud. Yoshi must defeat the Amazy Dayzee and hits the Winged Cloud to grow a beanstalk. At the top of the beanstalk, Yoshi can find a Paddle Wheel with more coins on it, some of which are Red Coins. He then jumps off to the left and hits another Winged Cloud, which reveals a staircase which leads to a clifftop with three Red Coins, a Flower, and a Fly Guy with an Extra Life.

Yoshi must head back to the Paddle Wheel and must get to the Middle Ring and must continue advancing throughout the level until the GOAL! Ring.
