Whippy is an enemy that debuted in Kirby's Return to Dream Land. It grants the Whip ability when swallowed. It made its second appearance in Kirby: Triple Deluxe, with the same form and function as before.
Whippy also appears very briefly in Kirby: Planet Robobot, appearing only in Stage 7-EX of Access Ark.
Whippy has an oval shaped body with vaguely feline features and a long, whip-like tail on top. It has orange whiskers on the side of its head, and its fur consists of warm colors, mainly reds and oranges. Whippy bears a dour expression, accented by its brow.
Whippy spins it's tail around in the air once, then snaps the whip toward the closest target. This has a decent amount of range to it, making Whippy rather dangerous.
