Behind the Waterfall

The Metal Cavern is a cave in Super Mario 64 that contains the Metal Cap's ! Switch. The cave is decorated by large glittering crystals and has a stream running through the middle. The water is moving fast and can sweep Mario out the caves one-way exit, the waterfall outside Peach's Castle. Upon entering the cave, Mario is automatically turned into Metal Mario and invulnerable to the streams current. Quickly defeat the few Snufits gaurding the switch and press it. All the green ! Blocks in the game will activate, gaining acess to the Metal Cap.

8 Red Coins are in the area, and several of them are just below a huge waterfall supplying the stream. The only way to reach them is with the Metal Cap.
