Bumper Ball

Bumper Balls are basically obstacles that are found in Yoshi's Story.

The Bumper Balls looks as it has four blue arrows pointing at each side of the Bumper Ball. These obstacles normally hook up with chain lines that appear on the screen. They also normally move at the left or right side of the wall. If a Yoshi bumps into one, the Yoshi will be bounced back. Additionally, some Bumper Balls are designed to move fast to bounce back the Yoshi hard. In some cases, the Yoshis can use these object to reach another part of the area in the level. These obstacles can’t be destroyed by throwing a Yoshi Egg or Ground Pounding on it. These obstacles only appear in the level, Lift Castle.
