Foos[1] are white cloud-like enemies that first appeared in New Super Mario Bros. Wii. They produce fog that can obscure the player's view. Foos can be defeated with any kind of attack. Their name comes from Fwoosh, a similar enemy from Super Mario 64 and its remake that blows wind.


Super Mario series[edit]

New Super Mario Bros. Wii[edit]

A group of Foos fire clouds at Mario

New Super Mario Bros. Wii marks Foos' debut appearance. They appear only in World 7-5, and create fog periodically.

The fog vanishes after a few seconds and can be blown away by Spin Jumping or propelling Propeller Mario.

New Super Mario Bros. U[edit]

In New Super Mario Bros. U, Foos appear only in Snaking above Mist Valley and behave the same as they did previously.

New Super Luigi U[edit]

Foos also appear in New Super Luigi U. Here, they are only found in Three-Headed Snake Block.

Mario Party 10[edit]

Foos play a role in the Mario Party 10 minigame Foo Me Once, where they blow fog over platforms the players need to remember.
