Mt. Molten

Mt. Molten is the volcano in the Melty Molten Galaxy in Super Mario Galaxy. There is a Sling Star above it, but if the Player drops into the volcano, there is a ground-pound switch on a rock floor at the bottom, which causes star bits to appear. However, the volcano will erupt 15 seconds after the Player presses the switch, so they have to use another Sling Star at the bottom to get out. In the Purple Coin mission (Red Hot Purple Coins), there are purple coins down the sides of and inside Mt. Molten. One coin in this mission is placed on top of a small lava ring inside the volcano, requiring 1 heath slice to reach it, unless the player uses a good timed spin.

Trivia

 * The eruptions of Mt. Molten are not classed as Lava Spurts.
