Kero Sewers

The Kero Sewers are an underground waterway in Super Mario RPG: Legend of the Seven Stars. They share a strong resemblance to the underground levels found in the original Super Mario Bros. with their turquoise color scheme and Brick Blocks. The Kero Sewers are located above Midas Waterfall and are guarded by Belome. Moreover, a tunnel in Land's End leads to the Kero Sewers, which Mario and his party enter to find—among other things—Cricket Jam, a star, and many monsters on the way.

The Kero Sewers also appear in Mario and the Incredible Rescue. Mario, Luigi, and Toad use this shortcut to get to Bowser's Keep faster. However, they end up in Cybele's forest and end up meeting her, who tells them to collect six Mushrooms. The first black Mushroom is in the Kero Sewers, which the gang then returns to. Piranha Plants roam the Kero Sewers here, although Piranha Plants did not appear here in the actual game.
