Wario Land 3: Part 94: Cave of Flames (Blue Chest)

Description:

The Rust Spray from Castle of Illusions' Blue Chest was applied to the iron walls of this third level, making them weak and brittle and easier for Wario to bash through toward a new part of the level. You'll find this rusty floor at 0:35. In the next room, Wario must rely on his high jump to reach the Blue Key; he can use enemies as platforms, throwing them up to higher platforms and jumping off them to trampoline himself further upward to obtain the key. To reach the Blue Chest, he goes into a neighboring room, climbs it, and becomes Flat Wario to cross a tight gap in the first room. The pair of scissors found in the Blue Chest is then used to cut the string of the big red balloon in Above the Clouds; the balloon floats upward to form a platform for a new doorway that Wario can enter.
