The Forgotten Grotto is a secret lot in Oasis Springs. Sims can access the area by breaking open and entering an abandoned mine entrance (requires level 10 handiness) that can be found deep within the canyon behind Desert Bloom Park, and also behind Affluista Mansion. A text adventure will begin, and the following options must be selected in order to visit the Forgotten Grotto: "Take the Wide Path", "Climb the Ladder", "Step onto the Ledge". After the initial visit, household Sims can simply enter the portal to travel directly to Forgotten Grotto. Sims with a level 7 wellness skill can teleport to Forgotten Grotto while meditating, if they have previously visited the area.
This area contains onion, sage, lily, potato, and mushroom plants, as well as mineable rocks, a fishing spot with the exclusive batfish, and a well in which frogs can be found. The Forgotten Grotto also contains a wooden toilet, so visiting Sims can relieve their bladder motive.
As the grotto is located within a cave, vampires are totally immune to the effects of sunlight here.
