From WiKirby, your independent source of Kirby knowledge.
Minny is a type of enemy in Kirby & The Amazing Mirror. It resembles a tiny Waddle Dee, about 1/4 the size of a regular one, with a mouth and bare hands and feet, which it crawls on.
Minnies are rarely encountered, most likely because they yield the Mini ability when inhaled and swallowed, which is of little use in most situations. When Kirby does encounter them, they are sometimes encased in walls, allowing Kirby to inhale them for their ability, but keeping them from reaching him in order to do harm. Minnies have no attacks, but merely run back and forth at a high speed, hurting Kirby if they happen to bump into him. They have a small amount of health, and may be beaten using any attack.
Minny may be found in Moonlight Mansion, Mustard Mountain, Carrot Castle, and Olive Ocean.
Additionally, Minny can appear from the gift boxes spat out by Boxy.
Kirby cooks up a bunch of Minnys in Moonlight Mansion.
