“Last time we weren't prepared, and you beat us like flat, little piñatas. But this time won't be so easy! Taste our paper power, punk!”
—Paper-Cone Goomba, Paper Mario: Sticker Star
Paper-Cone Goombas (known as Paper Cone Goombas in the PAL version) are a new species of Goomba that appears in Paper Mario: Sticker Star. In the overworld, they look like ordinary Goombas, but in battle they will take on their true form. Using sticker power, these Goombas can fold themselves into a conical shape, giving them a sharp corner that acts like a spike. Jumping on a Paper-Cone Goomba will damage Mario (the Iron Jump sticker must be used for the jump to be successful), and must instead rely on other stickers. The main attack of these Goombas is lunging at Mario like a paper airplane.
A trio of Paper-Cone Goombas attempt to stop Mario from getting the first Comet Piece in Warm Fuzzy Plains.
