The Dream Beach is an area accesible from the School through a hole in the wall of one of the classrooms.
Features
By entering the hole in the wall, you get to the inside of a pipe that Urotsuki must cross crouching. At the other end is a small underwater map, featuring some rocks, an NPC and a hook in the center. Interacting with the hook will take you to the Dream Beach.
The area consists of a beach with palm trees, a house and a small port with a lamppost and a kid fishing.
Interacting with the lamppost will make a ghost woman appear under it.
Inside the small house is a girl and an old woman sleeping. The girl reacts to the child effect by running out of the house. Outside, she keeps running a bit more, until she disapear with a laugh.
By interacting with the hook using the penguin effect, you get to what appears to be another underwater map with a fish that gets flat. Theres a valve to the right, if you interact with it, it will open and you will come out of a bucket next the kid fishing, and fall back to the water.
