Castle of Illusions

Castle of Illusions is a location found in Wario Land 3. It is located in the east side of the Music Box World. It will be accessible after Wario collects both of the Lantern of Truth (The Big Bridge) and the Flame of Truth (The Frigid Sea) and reveals the true appearance of the mountains in the east side of the Music Box World.

This level is a big, creepy castle haunted by Zombies who will try to turn Wario into an undead. If they manage to, the blue torches' lights can turn him back to his old appearance.

This castle also has red blocks that can be used as stairs. However, Wario must first activate switches to make them usable. The castle has several rooms, and almost each one of them has a chest and a switch. There is also a Brrr Bear in the first area that Wario can use to break solid blocks.

Gray Chest : Steel Overalls
To get this treasure and have a stronger ground-pound, Wario must first enter the first door and activate the switch. Then, he has to use the first two red blocks. He will then reach another door and activate another switch. After activating several switches and using several red blocks, Wario will find the gray key.

Finally, Wario must go back to the first room, and open the gray chest after pushing the heater to the right spot.
