Rock 'n' Fall

Rock 'n' Fall is the first level in World 4 in Yoshi's Island DS. To start, Yoshi must continuously jump onto rocks that, once Yoshi touches, will start to fall. Yoshi cannot stay onto the rocks for too long, or else he won't be able to jump high enough to get back onto the ground, and he will lose a life. Meanwhile, there are many Koopas and Paratroopas geting in the way. There are also some Piranha Plants that can get in the way. In the second area, Yoshi will have to Ground-Pound some of the rocks in order to continue. Yoshi should not touch all of the rocks, or else he will have to go back to the start of the second area. 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 appears.

Trivia

 * "Rock 'n' Fall" is a pun on Rock 'n' Roll.
 * This level seems to be a mix of the original's Visit Koopa and Para-Koopa and Lakitu's Wall.
