Artwork from Kirby's Adventure.
Wheelie is a recurring enemy, who appears in both Kirby's Adventure and Kirby Super Star. It resembles a tire, and gives Kirby the Wheel Copy Ability when swallowed. In the center of Wheelie is a large, reptilian eye; the most outstanding feature separating it from tires. There is a larger subspecies of Wheelie known as Grand Wheelie. While Grand Wheelie is a mid-boss, the standard version is a regular enemy.
