Cluckboom

Super Mario Galaxy
Bomb Chickens are chickens that lay eggs that explode after a few seconds. The eggs look similar to the boss Bugaboom 's uh, pellets. They are very hard to defeat, because they are incredibly high in the air. A well aimed Star Bit can however, make it fall down and you then can give it a good whack. If there is a Tweester nearby you can try to aim at the chicken's head. They are only in the desert galaxy, the Dusty Dune Galaxy.
