Sea of Dreams and Nightmares

This is how I imagine what lies below the surface in the world of Dreamzzz. A colorful coral reef, small fish and turtles swimming above it, but there are also dangers living here, such as a giant worm, clams with razor sharp teeth, and the cave nearby also stores an unpleasant surprise for anything that wanders too close to its entrance. The Nightmare king also left his mark around here, one of the sea anemones and an anglerfish are already under his influence (and what would that thing be hiding in the back?), and he also sent his admiral to find hidden treasures long lost to the sea. The admiral is not alone, however, whatever he may find, he will have to fight for it against Zoey's pet squid and the robot mosasaurus of Mr Oz.
