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.

Red Chest : Burning Torch
To get this treasure, Wario must first get the Golden Gloves from The East Crater. Then, he has to make his way to the Brrr Bear and use him to break the enemy blocks bellow, and use the new path to go outside.

Green Chest : Magical Powder

Then, he has to make his way to the Brrr Bear again and use him to break the enemy blocks and process. Then, he has to jump from a platform to another until he reaches a new area. Here, he has to use the first Hammer-bot to break the enemy blocks and process. He will then notice another one trapped inside a serie of red blocks. In order to use him, he has to enter the door found near him and activate the switch that makes the blocks disappear. Then, he has to let the Hammer-bot turn him into a Bouncy Wario. In this form, Wario has to make his way to the top and reach another area. The Green Key can be found here.
