Moleville Mountain

Moleville Mountain is a mini-game in Super Mario RPG: Legend of the Seven Stars. It involves Mario riding a mine cart on tracks. Mario controls the cart by leaning the direction he wants it to travel, if he fails to lean and is going fast enough he will crash on the corners losing time. During the mini-game Mario collects mushrooms to use as a speed boost and coins that you keep after the minigame. The first run through this mini-game is mandatory and part of the story, later on the moles make a tunnel directly to the game and charge 10 coins to access it (you can still reach it though the Coal Mines level as well). The moles keep a record of your time and reward you every time you beat your own time.
