Boo Blah



A Boo Blah is a kind of ghost that appears in Super Mario World 2: Yoshi's Island. This creature sticks to the ceiling or the floor, and jump up periodically. A large majority live inside Bigger Boo's fort along with other spirits and Boos. They are invincible, but are not a problem, they only hurt if the player somehow bump into them when they jump up. Stomping them stuns them for a little.

Trivia

 * They could have been the inspiration for Luigi's Mansion ' s Ceiling Surprises, who are similar to them.
