The Kero Sewers in the Nintendo Switch remake

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 the Midas River falls 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. If Mario enters the path to Land's End before using it to revisit the Kero Sewers, a Beezo will warn him that the area is a dead end.

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.

			Original	Remake
Flower		After using the pipe at the end of the first room, Mario should use the one next to it. In this room, he should reach another one at the bottom and use it to enter a room with yellow stairs. Here, he should go forwards to reach a treasure in front of yellow stairs.
Trueform Pin (first time) 5 10-Coins (second time)		In the same area, Mario should drop down to lowest level and go right to reach a treasure at the dead end. Jumping into this treasure triggers a battle with Huhwhat and Mario is awarded Trueform Pin after its defeat. After Mario leaves the room and comes back, this time the treasure contains five 10-Coins.
Star		After Mario comes back onto the upper level of the room with yellow stairs, he should reach the top of them and enter a pipe there. Upon exiting said pipe, a treasure is seen to the right.
Mushroom (lower chest) Flower (upper chest, first time) Cricket Jam (upper chest, second time)		After the water has been drained and Mario entered the previously unavailable pipe, two more treasures are seen. The lower one can be obtained normally, but the upper one has two methods of being accessed, each with its own reward (rewards are not mutually exclusive so both can be obtained without problem): If the Boo trick is used (go into the corner between the arch and the wall and let Mario be attacked by a Boo. Then run from the battle and use the blinking Boo as a platform to reach the top.), then Flower is rewarded. If the proper method is used (accessing Kero Sewers from Land's End via pipe), the Cricket Jam is rewarded.
