The water crystal is one of the four crystals hidden throughout the environment as of Alpha 0.0.82. It is labeled as Crystal (Unknown), possibly because a lighting effect similar to the light crystal or dark crystal is not yet implemented.
The water crystal is found in a boat on the small river to the right of Geoffrey's Parts Shop. Like all other crystals, it is floating. Swimming out to the boat is simple, although the player cannot jump while in water. The crystal is just at the edge of the player's reach when swimming next to the boat.
Touching the CrystalEdit
Unlike the two named crystals, the Light Crystal (Protection) and the Dark Crystal (Fear), the water crystal has no unique visual effect upon picking it up. It also remains labeled as Crystal (Unknown). This is possibly because it's development is not complete. This is similar to the fire crystal.
