Foo

Foos are cloud enemies that appear in New Super Mario Bros. Wii and New Super Mario Bros. U. They act much like a Fwoosh, though Foo's wind only produces fog and does not throw Mario away like Fwooshes did in Super Mario 64 and in Super Mario 64 DS. Foos do not have menacing demeanors like Fwooshes, and Foos can be neutralized, unlike Fwooshes. Mario can get rid of the fog produced by a Foo by doing a Spin Jump, however, if he is equipped with a Propeller Suit, he can clear the fog faster with the same method.

Foos can be defeated in all the same ways as other enemies, stomping them or using a Fire Flower. Foos can only be found in World 7-5 in New Super Mario Bros. Wii. In New Super Mario Bros. U, they only appeared in Snaking above Mist Valley.
