Mysterious Mine Carts
Mysterious Mine Carts is a minigame in Mario & Luigi: Superstar Saga. It is located in a cave on Hoohoo Mountain, specifically along the path that leads down the mountain and into the rest of the Beanbean Kingdom. The game is run by an old Beanish man.
In this minigame, Mario and Luigi must collect diamonds while riding mine carts along a set of tracks. Mario can make his cart jump by pressing the 
, while Luigi can do the same by pressing 
. The entire portion of Mario's track is visible to the player; however, only a small portion of Luigi's is, which is lit up by Mario using a flashlight. This light can be moved by using the 
. In addition to collecting diamonds, the brothers must avoid stalactite-esque Thwomps (the name of these creatures is unknown). Mario must also collect batteries, or else his flashlight will dim and eventually go out.
Mario and Luigi are required to complete this minigame during their first trip down Hoohoo Mountain in order to gain access to the rest of the Beanbean Kingdom. Ten diamonds must be initially collected the first time to gain a win. After this, the brothers may elect to challenge the game additional times to earn Hee Beans, with the number of diamonds needed increasing each time. At certain points during every level starting with level 2, bats who must be scared off using the flashlight swoop down from the ceiling. At level 5, a Boo wearing a mining helmet and wielding a pickaxe may appear to harass the brothers; Mario must use his flashlight to stop it in its tracks and make it disappear.
