Green Bit

Green Bit (グリーンビット) is an uninhabited island in the New World located north of Dressrosa. Law first mentioned the island when he was speaking to Smoker on Punk Hazard.

Geography
Green Bit is connected to Dressrosa by an iron bridge. The presence of the Fighting Fish has forced the bridge to be closed for 200 years.

Befitting it's name, Green Bit is a very green place, with a large forest and huge plants. Some animals, namly Wolves and Boars have been seen on the Island.

Past
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.

While on their way to Green Bit, Law, Usopp, Robin and Caesar asked about Green Bit and discovered that it is guarded by Fighting Fish and the only way to the island is across an iron bridge.
