About this build

A rock rising out of the sea, hollow inside, with an arch at the waterline into a grotto. Inside, the sea fills a pool lit from its floor, steps climb out of it to a ledge round the back where a throne of prismarine stands under a lamp, and a giant clam of pink and purple holds a white pearl. Lights glow in the rock walls, coral grows on the pool's floor and round the rock outside. The rock is hollow behind its walls.
