The darkness of the seabed

Exploration Stage: Itallian Patio
From: Valerie
Description: I'm sure the next scene will make everything clear. It's the scene where the hero rescues the heroine from the dark depths of the ocean. The stage prop we need to look for here is, um... "a man-made seabed"! Nothing could be more terrifying than to see something like this in action.
Completed: So this is the undersea landscape... and like most props, I can't read the signature clearly. But don't worry. We should be able to solve the mystery soon.
