Boxy

Boxy is a mid-boss who resembles a box with a bow on her head and a stem and leaf as a tail. She may try to ram Kirby or spit smaller boxes at him. Kirby can spit the boxes back at Boxy. If Kirby goes near a box it will open revealing the following: When Boxy is defeated, Kirby may inhale her for the Magic ability.
 * a Battery (only in Kirby & the Amazing Mirror)
 * a Minny (only in Kirby & the Amazing Mirror)
 * a Bomb
 * a piece of Food
 * a Waddle Dee

Boxy also appears in Kirby: Squeak Squad. Her behavior is the same. However, the boxes only contain Waddle Dees, a bomb, food, and very, very rarely, a 1up.
