Rainstorm Lake is the the third level in Luigi's World. It's unlocked after beating Bowser's Castle in World 8.
It's a simple rainy level (like Koindozer Forest) with no ASM tricks.
The stage has a glitch: for some reason it can pixelate the screen as Mario advances through it. When Mario beats the level, the Overworld will glitch up whenever the player change submaps with a exit tile.
Music[]
The music used in this level is the normal underwater theme from Super Mario World.
