Blue Lagoon (Japanese: ブルーレイク Blue Lake) is an anime-exclusive large lake located on Blue Point Isle that contains a colony of Chinchou. Long ago, the land where present day Blue Lagoon sits was at the bottom of the ocean, it is theorized that the Chinchou's nesting ground was located here. Then, a volcanic event occurred and raised the land until it formed present day Blue Lagoon, complete with a large lake that Chinchou return to in order to nest. There is a town settled around Blue Lagoon, and, due to the migrations the Chinchou of the lake undergo to return to the ocean, the town hosts a festival around the event called the Parade of the Chinchou.
