Rock 'n' Fall

Rock 'n' Fall is the first level in World 4 in Yoshi's Island DS. Its name is derived from Rock 'n' Roll.

Layout
To start the level, Yoshi must continuously jump onto rocks that, once Yoshi lands on, will start to fall. Yoshi cannot stay on the rocks for too long, otherwise he will not be able to jump high enough to get back onto the ground, and he will lose a life. In the second area, Yoshi will have to Ground Pound some of the rocks while avoiding enemies in order to continue. In the third area, Yoshi needs to jump on more falling rocks while avoiding the Wall Lakitu. In the final area, the screen will start auto-scrolling. Yoshi must both avoid being crushed by the rocks above him, while jumping on the right rocks beneath him. When Yoshi makes it to the top, the goal roulette appears.
