Leeches

Leeches are a water-based enemy in Rain World. They live solely in water 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. The common variety is small and tinted red.

''They are not a source of food. (dead or alive)''

When the player ventures into their territory leeches will attach to your Slugcat. Leeches have been shown to jump out of water and team up to take down prey. Many leeches will weigh the Slugcat down, and may make it hard to get back to land. Once on land, the player should attempt to shake off the leeches quickly.

Blue Leeches
Blue leeches are a bigger version of the normal red leech, they are harder to dehydrate and are very heavy and fast. The blue leeches are found in the transition from Garbage Wastes to Shoreline, and throughout Shoreline.

Interactions with other creatures
Bats that hover near the water's surface have been known to be attacked by leeches, and subsequently eaten. Leeches will also attempt to consume scavengers and even vultures. Squidcadas may be seen preying on leeches.

However, in order to bypass a leech, it is possible to distract them by throwing food (such as bats or flies) into the water. The leeches will disappear for a few moments, allowing Slugcat to swim past unnoticed.
