Wario Land 3 - Above the Clouds (Blue Chest)

Enter this level at night after the Full Moon Gong summons the moon and get the Blue Key once you reach the moon. Enter the door on the moon and hit the turf to make spiked rays float. Throw a rock at the blocks and enter the next door. Bounce off a Blue Bird by ducking and cross falling platforms. Do one last jump by breaking the blocks and open the Blue Chest. This chest contains a Pick-Axe. This item will open a warp portal at The East Crater.
