Colossal Coral

The Ocean biome is a flat expanse of dark, open water that divides islands.

Terrain
The ocean consists of dark water, which gives way to lighter water near land where the seafloor rises. The seafloor consists only of the stone of the underground. Nothing spawns here, though aquatic vehicles used to traverse it may appear on adjacent beaches.

The player can swim through water, as can all characters and creatures. The Dinghy and Small Submarine provide options for fast travel across it. Wheeled vehicles are destroyed if they spend too much time in water.

There is no way to go down into the water from the surface, despite the names of the Small Submarine and Diver. It is possible to swim around if the ocean is entered from below, but the player will quickly be forced to the surface. This also applies to characters, creatures, and vehicles who are pushed in.

Water can be broken by the Remove Terrain tool or by explosions.

Exploration
As the ocean is featureless, it serves as an obstacle to exploration. Aquatic vehicles and flying vehicles or creatures are useful for making the crossing.
