Foos are white cloud-like enemies that appear in New Super Mario Bros. Wii, New Super Mario Bros. U, and New Super Luigi U. They produce fog that can obscure the player's view. Foos can be defeated with any kind of attack. Their name comes from the Japanese onomatopoeia for blowing sounds.
New Super Mario Bros. Wii
New Super Mario Bros. Wii marks Foos' debut appearance. They act much like a Fwoosh from Super Mario 64 and its remake, though Foo's wind only produces fog, and does not blow Mario away. They appear only in World 7-5.
New Super Mario Bros. U
New Super Luigi U
Super Mario 3D World
Although no original Foos appear in Super Mario 3D World, a new subspecies called Ty-Foos are introduced. Ty-Foos function more as obstacles rather than enemies. They blow a strong gust of wind that pushes the player and projectiles, such as Fire Flower fireballs, in the opposite direction, usually into another obstacle such as spikes or a pit. Heavy enemies like Bullies are unaffected by the Ty-Foos' gust. Most Ty-Foos are stationary, but some can move left and right while blowing. They can be stunned with fireballs and boomerangs, but Ty-Foos can be defeated only by star invincibility, an Invincibility leaf, or a Mega Mushroom.
