Yoshi's Woolly Woods is the first track of the Special Cup in Mario Kart 9.
Yoshi's Woolly Woods is a course made entirely of yarn, like the video game Yoshi's Woolly World. The stage starts out in a Yarn Yoshi village, as Yoshis, Toads and Shy Guys watch. The race goes through several rolling hills of yarn, until the player reaches the actual forest. This takes the player through a forest of woolly trees and sunflowers. The sunflowers act as obstacles, but some have leaves low enough to the ground that you can perform tricks off of. The race is then taken to a flowing river (where the water is yarn) which has several boosties. The players then race back into the village for a short drive, and then reach the finish line.
