Big Bubble

Big Bubbles, as their name implies, are huge, invincible green bubbles that appear in Super Mario World. They only appear in the Ghost Houses and if jumped on or touched by Mario or Luigi would get hurt. It is very big, and can block paths, which can be a very annoying obstacle.

They reappeared in the Wario's Carnival Ghost House in Dance Dance Revolution: Mario Mix, but have not since appeared.
