Big Bubble

Big Bubbles, also referred to simply as Bubbles, as their name implies, are huge green bubbles that appear in Super Mario World. They only appear in the Ghost Houses and if jumped on or touched in any way, Mario or Luigi will be hurt, with the exception of using a Slope Slide which actually destroys them. They are very big, and can block paths.

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