Green Bit is a seemingly uninhabited island in the New World located immediately north of Dressrosa. Green Bit is connected to Dressrosa by an iron bridge and also, as it was later revealed, by a secret underground passage. The presence of the Fighting Fish has forced the bridge to be closed for 200 years.
Befitting its name, Green Bit is a very green place, with a large forest and huge plants. Some animals, namely birds, foxes, and boars have been seen on the Island. Underneath the forest, there is a village which is formed by plants. Until 200 years ago, the island was visited regularly by the citizens of Dressrosa. However, the arrival of Fighting Fish made travel across the bridge impossible. Since then, nobody who has traveled across the bridge has been known to return.
