It leads to a cactus sitting in what appears to be the last of the water in the entire area. There is an alternate entrance here from Atlantis if the screen is tinted red, a uniquely shaped piece of coral in the Trench area will serve as a one-way portal to this area. Along this path is a rusted vending machine which sells broken, empty cans for 10夢 and several broken ships on the ground continuing west from here will take you to The Ark.
By chainsawing the cloaked figure and entering the corridor, you will be taken to a path scattered with pieces of broken ships, sea urchins, and crabs. North-west from the entrance is an NPC in a yellow cloak near a wire-fenced corridor. A slug will also show up south of the isolated wire-fenced area, who will take you to Mangrove Forest when interacted with. If you make it rain with the Teru Teru Bōzu effect, the sky will turn dark and all of the cacti will turn into hands, reaching up towards the rain.
Directly to the west is a fenced-off area with a small cabin, which takes you to the Ash Settlement when entered. Despite the setting, several organisms remain alive and well here, including crabs, some sea urchins, and some small mites that run directly away from the player when touched, as well as a huge dead fish. When entering, the Scorched Wasteland is a red-tinted area containing cacti singed black, possibly the bed of a dried-up sea.
