This papercraft is Chilly, a snowman-like foe who tries to freeze Kirby with his wintery powers, and is a regular enemy in the Kirby series, the paper model was created by aardonix. Kirby can get either the Freeze or Ice ability from it depending on the game.
Chilly is a snowman made of two balls of snow piled on top of each other. Its hands are yellow or blue balls attached to the middle of its two segments. Chilly wears a bucket on his head which simulates the role of a small fez-like hat. The only facial features Chilly sports are big black eyes with overt angry-looking eyebrows over them. Chilly wears a bell around his neck, but this was sometimes absent in earlier games.
Like other enemies, Chilly comes in a variety of different color palettes. Most common is blue, which serves as his Helper coloration in Kirby Super Star. Another palette, which was popularized by the anime, has a green hat with a maroon collar. This first served as an alternate palette in Kirby Super Star, returned as one of several other alternate palettes in Kirby: Nightmare in Dream Land, and was the normal coloration for Chilly in Kirby's Return to Dream Land.
