Wario Land 3: Part 18: The Big Bridge (Red Chest)

Description :

Now that Wario has the Swimming Flippers, he can finally swim underwater again. In The Big Bridge, find an underwater path lying just under this bridge. It will be full of enemies, but all they can do is send Wario upwards a bit. There are Brrr Bears here that freeze Wario into Ice Skatin' Wario and force him backwards until he hits a wall, but you can take advantage of this to knock another bear out of the way towards the Red Chest to the right, and the Red Key in a hole next to it. The Big Bridge's Red Chest Treasure is the Cyan Crayon, which will color in the sky of the GAME spot that Wario walks past between the North and West Sides of the world.
