Bouncy

Bouncies are pink bubble-like things in Yoshi's Island DS. If one is touched, the character who touched it, will bounce back a few feet. Sometimes these circular creatures can help the Yoshis by making them bounce a few feet in the air and letting them reach high places. The boss Six-Face Sal is similar to them, except the boss can't be bounced on. They are prominently featured in the minigame Bouncy Maze.

Bouncies first appear in Level 2-5 of Yoshi's Island DS; this level was called "Boing!".

Trivia
In the level "Teeth-Chattering Chill Zone", Bouncies that are bouncing off of the platforms can be slightly knocked backwards by hitting them.
