Bramball

Bramballs are a new type of enemy found in New Super Mario Bros. Wii, found solely in Toxic Forest. 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.

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".
