Midas River is a stage found in Super Mario RPG: Legend of the Seven Stars for the SNES. After defeating Belome in Kero Sewers, Mario and Mallow were discharged into the river and automatically fell all the way down. Here the player could direct Mario in attempt to grab the multiple different coins and Frog coins; however if they were to fall into a cave, Mario would spiral down into an enemy infested subterranean where the player would likely loose a hefty amount of the coins they had just contained.
Following this delightful voyage, Mario will fall on top of a barrel and start to flow down a river in another attempt to nab as many coins as possible. In this minigame styled event, Mario could switch barrels by ramming into it. To collect coins, the player would be required to press the jump button at the right time.
