The Octans Coin is one of the one-hundred Constellation Coins the player can collect in Endless Ocean: Blue World. It can be found occupying a zoom-mode patch in the Cortica River area at coordinates B-1, placing it on the path through the relatively perilous area known as the Mangrove Maze. This means that there is a chance that the player may encounter an Electric Eel or two while searching for this coin, so it is advised that caution is taken when looking around the area.
