Accordion wall

Accordion walls are objects that appear in Yoshi's Woolly World, Poochy & Yoshi's Woolly World, and Yoshi's Crafted World. They are walls made of fabric that, when a Yoshi pushes them, contract like an accordion and either unveil collectibles or allow the Yoshi to reach an area secluded by them. While accordion walls are semi-common throughout the former two games, the latter game also features them in the level Stitched Together.
