Wario Land 3: Part 78: Castle of Illusions (Green Chest)

You'll have to use some Switch Blocks again to go for another climb, but this time, take the same route you took before to get to the Red Key, and head to the room at 1:21. With the Super Grab Gloves, pick up the robot and throw him through the Enemy Blocks into the other side of the room. Go through the doorway there and find a Switch Block that shifts around the red blocks in the bigger room. This will release another nearby robot that you can use to turn Wario Bouncy and bring him up to a higher floor. This will lead to a room that contains the Green Key. Now go all the way back and go into the room with the Green Chest at 4:00. Castle of Illusions' Green Chest Treasure is... Gold Magic! This magical wispy sand then makes its way towards a giant faced tree in Out of the Woods, causing it to open its mouth for a new doorway to reach in that level. Oooooh... Going back to the very first level on last time, eh? Surely this will lead to something great!
