Bomb Boo

From the Super Mario Wiki

A Bomb Boo is an explosive, black-colored variety of Boo. They are enemies found solely in the game Super Mario Galaxy. Bomb Boos have so far only made appearances in the Ghostly Galaxy, during the missions Beware of Bouldergeist and Bouldergeist Daredevil Run. Bomb Boos float lazily back and forth, exploding after some time, but they do move towards Mario or Luigi. If the player Spins near one, Mario or Luigi will grab its tongue, and it would get spun around until it hits something, or if Mario or Luigi's grasp weakens.

If the player holds it for too long, it will begin to flash red. If the player doesn't let go of it then, the Bomb Boo will explode, injuring the player.
