Big Boo's Beach

Big Boo's Beach is a course that can be found after unlocking a room in Princess Peach's Castle using Big Boo's Key in the Castle Basement. It is a long, rectangular beach with several Boos and Scuttlebugs, and an underwater segment nearby with new enemies called Boo-Bubs that are Boo versions of Bubs, as well as a Unagi. There is fog re-used from Jolly Roger Bay, and a stormy skybox.

Geography
This course is divided into 2 halves: the beach and the ocean. The beach is a rectangular strip of sand with several Boos and Scuttlebugs with a structure in the middle of the beach known as the Sand Mansion that is a mansion known as sand. In the ocean, there are several Boo-Bubs in the water as the map goes deeper as the closer to the edge the map gets. At one point, there is a large rock with a tunnel inhabited with a Unagi.
