Bramball

Bramballs are a type of enemy found in New Super Mario Bros. Wii, found solely in World 5. They appear as spherical Pokey-esque enemies with brambles for arms jutting out of their sides. Their sole attack is moving around a set path by flipping themselves around. When they reach the end of a small island or flat end, they will continue and flip the other way.

Bramballs can be defeated by jumping on the ball in the center, freezing them as Ice Mario or Penguin Mario and Ground Pounding on them while frozen, being hit by Fire Mario's fireballs and a Star. Hitting them from underneath will release coins. They have feet similar to that of Plungelos.

Trivia

 * Bramball's name is a play on the words "bramble" (of which its long appendages are made out of) and "ball".
