Leeches

Leeches are currently the only water-based creatures. They thrive solely in their liquid homes, and if they find themselves on land they will attempt to shimmy back to nearby water. If they fail to reach water quickly they dry out, wither away, and die. It is unknown if leeches, dead or alive, are a source of food.

If the player ventures into water it is likely that leeches will attach to you. Many leeches will weigh you down, and may make it hard to get back to land. Once on land, though, the player should attempt to shake off the leeches quickly.

Careless bats that play near the waters surface have been known to be 'attacked' by leeches, and subsequently drowned.
