Kapar is a green duck enemy with webbed, dark green feet and round eyes. He first appeared in Kirby's Dream Land 3 and later in Kirby 64: The Crystal Shards. He sits in one place, and occasionally jumps up and throws his spiky, hollow, darker green hat that is on the bald top of his head at Kirby. He is also capable of swimming. Kapar gives the Cutter ability. In Kirby 64: The Crystal Shards, a giant Kapar appears in Aqua Star Stage 3 as the mini-boss, with two Bumbers to spit out at him. This also makes the giant Kapar the first mini-boss to not have smaller versions of himself for Kirby to suck in and spit back at him, but instead different enemies from himself. Kapar's card is #43 on page 5/9.
Kapar is loosely based on the mythical Japanese monster, Kappa. He slightly resembles Kap'n from the Animal Crossing series, who is also based of the Kappa.
