ivory lily
so i think that when you go down to sewers and kill red light green light a tunnel appears and when you go through you get chased by a big blue fish and if you reach the end there is a room that is like black neon green neon blue and neon pink and the crystals i think should be like lava but they drop a small ball and sell for 400 to 500 each oh and also there is a big blue fish in there as-well. and the other crystals should be the same like look the same as the lava ones but are pink blue and green and there should be a giant tree that has crystals that sell for 1k each but 2 others are protecting it
