Bomb Boo

A Bomb Boo is an explosive, black-colored variety of Boo. They are enemies found solely in the game Super Mario Galaxy and its sequel, Super Mario Galaxy 2. Bomb Boos have so far only made appearances in the Ghostly Galaxy, during the missions "Beware of Bouldergeist" and "Bouldergeist's Daredevil Run", and in the Boss Blitz Galaxy, during the missions "Throwback Throwdown" and "Throwback Throwdown Speed 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. Also to note, sometimes Bouldergeist will punch them and they will disappear.

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 (though by continuing to spin, the Bomb Boo can be swung wider and faster until he flies out of Mario's grip or hits something).

In Super Mario Galaxy 2, Bouldergeist re-appears, along with four other Super Mario Galaxy bosses, in the Boss Blitz Galaxy. Because of Bouldergeist's re-appearance, Bomb Boos made a comeback (so Mario could damage the boss).

Trivia
