Kuribo's Shoe is a rare power-up first seen in level 5-3 in Super Mario Bros. 3
for the NES. It is first mentioned after you beat world 2 in a letter given to you by Princess Peach
. The name "Kuribo's Shoe" comes from the fact that in the Japanese version of Super Mario Bros. 3, Goombas
are known as Kuribos. A second revision of Super Mario Bros. 3 was released that renamed Kuribo's Shoe to Goomba's Shoe, though in its appearance in Super Mario All-Stars
for the SNES, it had reverted to its original name.
Kuribo's Shoe is a giant green boot with what appears to be a spring-winding key on the side, and it is initially occupied by a Goomba. While attempting to jump on top of Kuribo's Shoe while still occupied by this Goomba will eliminate both Kuribo's Shoe and the Goomba, attacking from underneath knocks the Goomba out of the shoe, making it possible for Mario
to take control. While Mario's speed is reduced while in Kuribo's Shoe, he's able to traverse terrain that would otherwise harm him. These terrains include spiked floors and jumping baby pirahna plants
. Unlike other power-ups, it is possible for Mario to keep his current power-up (e.g. Fire Flower
) while using Kuribo's Shoe.
