Cloud Cruising

Cloud Cruising is the aerial level 3-1 in Yoshi's Story. In this level, the Yoshi most ride on snakes that climb higher and higher into the sky. Also in the level is the friendly green Dragon that the Yoshi can ride while it curves up and down. Shy Guys fly around directly in front of the "pathways" so be careful not to hit them.

Trivia
The level 7-3 in World 7 of New Super Mario Bros. is partly based off Cloud Cruising, as one section has an area where Mario rides on a giant Wiggler, similar to the area where the Yoshi rides on the Dragon.
