Unagi's Tunnel

Unagi's Tunnel is the name given to a sub-area that can be accessed in Jolly Roger Bay. It is usually accessed by swimming into the tunnel Unagi the eel inhabits after the Plunder In The Sunken Ship mission. It is a large, linear underwater cavern with several Unagis that swim through it. There are small areas in the ceiling the player can use to regain breath. Upon swimming to the end, the player can collect a star.
