Choppah

Choppahs are a type of enemy appearing in Super Mario Galaxy 2. They appear as green creatures that lack legs. Each Choppah has an orange spiked helmet and has a propeller around it, giving the enemy the ability to fly. Its name is a corruption of "chopper," an alternate term for "helicopter," referring to the enemy's propeller. Choppahs fly in a vertical straight line in most galaxies.

Choppahs first appear in the Honeybloom Galaxy as the main obstacles. These enemies later appear in the Sweet Mystery Galaxy (where they are only seen flying horizontally), Honeyhop Galaxy, and Flip-Out Galaxy, as well as during the Grandmaster Galaxy's mission The Perfect Run. These enemies can be defeated only by being eaten by Yoshi and release three Star Bits upon being eaten. Most of the time, they appear when the player must traverse through a 2D pathway. They are less common when the pathway is 3D, mostly appearing when the platforms are narrow or have less ground. When shot by a Star Bit from the Star Pointer, they get stunned in place for a short moment.

Trivia

 * The body structure and behavior of Bees from Donkey Kong Jungle Beat are very similar to Choppahs'.
