From WiKirby, your independent source of Kirby knowledge.
Puffy is an enemy which appears exclusively in Kirby's Dream Land, found mainly on the Bubbly Clouds stage. It is a flying cloud-like foe which is capable of shooting projectiles, and is worth 600 points when defeated.
Puffy only appears in the main game. In the Extra Game, it is replaced by Cawcun instead.
Puffy resembles a white puff of smoke with a pair of heavy shades. It is often found flying in swooping motions through the air, reaching its top speed when in the middle of its arc. These arcs can vary in height, and may aim upward or downward. Puffy is also capable of firing a triple spray of round projectiles which travel slowly, though it requires a fair amount of time to get this attack out. Most of the time, it will end up harming Kirby by collision if it does so at all.
