Kirby Mass Attack sprite
Illusion Door resembles a normal door. It has an evil expression on its face, a vicious mouth, and magenta bat wings.
Illusion Door appears exclusively in Stage 7 of Volcano Valley. It does not attack the Kirbys, but when it appears, the area darkens, and Illusion Door switches around with a normal door. The Kirbys must then guess which door is the right one. If they enter the enemy, it takes them to a small room containing one or more enemies; the Kirbys must defeat them to escape. The most common enemies used in a Illusion Door trap are Mossys; semi-commonly, a Big Stactus; and rarest of all, Slugoos.
Illusion Door cannot be defeated without Invincible Candy.
