Not going to explain too much in this picture but yeah... This is Baton Island. It's a giant Bat-shaped Mothership.
It's split off into multiple sections, the upper half is a giant "summer resort" for the Fruit Bats to eat all the fruits they want and fly around and take baths and stuff, the under-half is for every other species of bat that is nocturnal or crepescular and is themed after a set of caves and forests with heavy canopies. The head is a set of server rooms, mission control, and cockpit for the captains, and the back section is the Red Yard, presumably where Melancho gets shafted to for his duties.
You figure out what the secrets of the mothership are, I'm not explaining it here.
