|“||This scrappy little fish has just one goal in life: to swim straight up a waterfall. He's had that dream for a while, though. Maybe he's worried about what comes after he's reached the top of that metaphorical waterfall.”|
|— Figurine description • Kirby and the Rainbow Curse|
Carpa is a round fish. He has a white underbelly, fins, and a circular mouth. The fish's top side is red with a tiny dorsal fin and a curvy white line dividing his front and back. His posterior boasts a small red tail fin. Carpa wears a lazy expression at all times due to his partially-closed eyelids.
Carpa appears exclusively in the stage Great Cave Escape. He is often found swimming up a waterfall, sometimes carrying an item. If the player draws a rainbow rope in a part of the waterfall above the fish, he will fall to the ground, still holding the item. When on land, Carpa will haphazardly hop across the ground in one direction; he will turn around if he hits a wall or approaches an edge. If the fish hops into a waterfall, he will swim up it.
Carpa's name is derived from "carp," a species of freshwater fish.
