Tatami Block

"Don't just stand there! Slam that block's switch to make a platform extend."

A Tatami Block is a large block that appears in the World 5 fort and castle levels in Yoshi's New Island, in both Ready, Steady, Go! and Punkey the Pokey Prince's Castle. When ground pounded on, it causes more blocks to spawn from it, unfolding and going in a certain direction. After a particular amount of time has passed, the platforms despawn, flipping back inside. The block is named after  mats, named after their ability to fold.
