Foo

Foos are a new cloud enemy that appear in New Super Mario Bros. Wii. Their only appearance in the game is in World 7-5.

They act just like a Fwoosh, though its wind only produces fog and does not throw Mario away like Fwooshes did in Super Mario 64. Mario can get rid of the fog produced by a Foo by doing a Spin Jump.

Foos can be defeated in every way possible existing in the game, though some of them are in places that Mario can't access.
