Wario Land 3: Part 100: The Vast Plain (Blue Chest)

Description :

The Red and Blue Chemicals were combined to create a solution that softens the ground right under the 5‑ton blocks in this level, causing them to sink. I head towards the new path this created at 1:10. The next room involves heavy use of Invisible Wario to pass through a gate that guards the Blue Key, requiring tight platforming because Wario must be invisible. A deeper room within this room contains the Blue Chest, but the layout to reach it is invisible instead; the enemies found here may help show you where you can land. The Vast Plain's Blue Chest Treasure is the Red Gem—just another shiny thing to keep. Just one more treasure to go; Part 101 will be the grand finale of this playthrough toward a perfect finish.
