Kirby Mass Attack sprite
Illusion Doors are enemies in Kirby Mass Attack. They resemble a normal portal, but they have evil expressions on their faces, vicious mouths, and magenta bat wings.
Illusion Doors appear several times in Stage 7 of Volcano Valley. They don't attack the Kirbys, but when spotted, the background will turn dark, and Illusion Doors will switch around with a normal portal. The Kirbys must then guess which portal isn't a Illusion Door. If they enter a normal portal, the Kirbys can continue their adventure. However, if they enter a Illusion Door, it will take them to a small room, where the Kirbys have to fight some enemies, so the player has to choose wisely. The most common enemies used in a Illusion Door trap are Mossys; semi-commonly, a Big Stactus, and rarest of all, Slugoos.
