Futā Road

Futā Road (フターロード, Futā Rōdo) is a world associated to the Star World, appeared in chapter 12 of Super Mario-kun volume 2.

While looking for the real Star Road that will take them to Star World, Mario, Luigi and Yoshi find a Star Road that takes them to Futā Road, a World similar to a cooking pot with a lid. While exploring one of Futā Road's levels, Mario eats a Poison Mushroom, which shrinks him. Luigi looks in a Rotating Block for a Super Mushroom, but the block punches back: in Futā Road, people have to ask for an item to blocks, and the aforementioned block doesn't have a Super Mushroom.

Yoshi finds a Keyhole from which they'll be able to return to Dinosaur Land and, after defeating a Sumo Bro, the trio exits the Futā Road.
