Mt. Molten

Mt. Molten is a volcano found in the Melty Molten Galaxy in the game Super Mario Galaxy. There is a Launch Star above it, but if Mario 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 fifteen seconds after Mario activates the switch, so they have to use a 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 one health slice to reach it, unless the player uses a good timed spin or a Long Jump.

Trivia

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