Wario Land 3: Part 79: Out of the Woods (Blue Chest)

The last treasure of the first level is the Blue Chest. The Gold Magic from Castle of Illusions' Green Chest opens the mouth of a huge tree, which serves as a doorway into a hollow tower. (NOTE: If you don't transition into the next room from climbing the ladder at 00:55, you'll need to reset and reload your game.) Climb as high as possible to find a hole that drops you to the Blue Key left of the tree; you may fall out of the tree entirely, but you can climb back to the top later. After reaching a warp pipe, you encounter the spider boss Anonster. Avoid the webs he shoots from his mouth, or Wario will become Ball O'String Wario and roll out of the tree. Let the webs fall to the ground, where they turn into web balls that can be picked up and thrown at Anonster, forcing him to drop on top of you. Dodge his attacks, then ground pound him to damage him; as he takes more damage, his abdomen changes color, eventually turning red, and he shoots more webs to try to tie Wario up. Squish the spider, and you can reach the level's Blue Chest, the fifth and final music box. With all music boxes collected, Wario can bring them back to the Temple to release the Hidden Figure.
