In Kirby & the Amazing Mirror, Wiz is a boss that appears at the end of the frosty Peppermint Palace. When Kirby (and any allies he has with him) enter the arena, Wiz floats down to the middle of the screen in his hat. He fights Kirby by rushing to different points of the screen, and, by going inside his hat, summons a multitude of obstacles to attack Kirby. Whenever he is inside his hat he is invincible, so Kirby will have to attack him before he hides inside it.
Most of the objects that Wiz makes, which range from actual enemies to common household items, don't give an ability. Only three of the objects do, and one of them, the flashing Poisoned Apple, gives the dangerous and unhelpful Sleep ability.
