Corroborated
Forest
The second island, reached by boat rudder. Home to a leech-collection quest, Giant Piranha, Sunfish, and The Old Pike.
"Forest" is corroborated by two independent fish-list sources. The leech-collection quest is corroborated by a guide source and the gameplay video independently. Sunfish and The Old Pike are both placed on this island by Game8's boss table; The Old Pike's placement here is new information not previously linked to a specific island.
