The Submarine Shrine is an important boss stage in Stick Ranger. It is represented on the map by an outline of a blue castle over the water in the east section of the bay. Its location is revealed at the start of the game, like the Castle stage before it. Likewise with the Castle, there are two levels in this stage: the first being the entrance to the castle, and it does not contain any monsters. The second holds the second mega boss, the Submarine Shrine Boss. This stage, like the Castle stage before it, may serve as a kind of 'barrier' to the next part of the world map, the Desert. It is a much tougher stage than the Castle, so it is recommended to come very prepared before taking on the boss.
