Flooff

Flooffs are small fireball creatures that appear in Yoshi's Woolly World. They attack by hopping towards Yoshi similar to Fire Snakes. Yoshi can grab a Flooff's flame with his tongue, rendering the Flooff vulnerable to attacks, and use the flame to breathe fire, albeit only once. While unlit, it will not hop as high or as fast, and Yoshi can defeat it with a stomp or a yarn ball. However, after a short time, or if Yoshi breathes the fire back at the Flooff, it will light it back up. Flooffs also cannot be eaten. In the course The Desert Pyramid Beckons!, Flooffs are used to light torches in certain rooms like the one that is studded with rubies. And in the first course of world 5, they can be ultimately defeated by a rolling snowball when Yoshi comes out of the green pipe exiting the underground cavern.
