Kirby Mass Attack sprite
Floof is a white cloud that will hover in place, while carrying fruit. If Kirby comes near, it will try to fly away from him. Kirby must catch up to it and attack it (with the aid of his clones) to defeat it before it gets away. Afterward, the little hero will be rewarded with the fruit. A more dangerous version called Flickerfloof also appears.
Floof's name may be a pun on the word fluff, which is used when describing clouds as fluffy.
