It can be used to create drinkable water. It provides -5 Food and +15 Water when consumed. The **Digestion** adaptation is required to safely consume alien lifeforms. A player without this adaptation will not receive its effect and be deducted health.+The **Water Slug** is a small, bottom-dwelling lifeform that is incapable of significant movement. It can be used to create drinkable water. It provides -5 Food and +15 Water when consumed. The **Digestion** adaptation is required to safely consume alien lifeforms. A player without this adaptation will not receive its effect and will lose health.  +![Water Slug](Water_Slug.png)+  ## Appearance  -Water Slugs have a large muscular foot, atop of which is a largely transparent body with four backward-facing spines and a purple inner core. The head is purple and has a triangular mouth with a pair of eyestalks.+Water Slugs are small creatures with semi-translucent bodies. They have a large, long, muscular foot that is purple in color, with cyan specs seen around it. A large translucent bulb sits atop the foot, inside of which they possess a lengthy spiral gut, similar in shape to a coil. Four appendages grow out of the bulb at the back, two on each side of the body. Their color fades from cyan to yellow.  +The Water Slug possesses a small head present at the front, which is pink in color, featuring a yellow stripe going through the middle. Two eye stalks spread out from the sides of the head, with small golden eyes present at the ends. The mouth ends with a sharp, wide beak.+  ## Behavior  -Water Slugs can be seen hiding within patches of seagrass where they remain motionless. When a player approaches, Water Slugs will contract their eye stems and shake.+Water Slugs are completely motionless. They can be found around most of the world in various places, usually hiding in foliage.  +When the player approaches a Water Slug, it retracts and begins to shake until the player moves away. If observed from afar, Water Slugs can be seen performing a variety of idle animations.+  ## Databank Entry  -**Source:** [Scan](Scan) a Water Slug-  **Water slug** (tentatively *Seaslug hydroclast*). A biological enigma that converts seawater into drinkable fresh water.   1.  **Microbial fuel cell**: Removing salt from seawater is energy-intensive. Nonetheless, the water slug does it, perhaps as a byproduct of an internal microbial reactor that feeds on waste in seawater. 2.  **Fresh water reserve**: A hydrophobic plastic bulb that protects the slug from rapid dehydration by saltwater. 3.  **Plankton farm**: The slug's water bulb hosts a highly productive plankton species, turning light into food. Fresh water may be necessary for the plankton's chemistry, or it may be a prison—a way to keep the plankton from leaving. 4.  **Vampiric aura**: The water slug's developed beak has a sharp cutting surface. Possible evolutionary history as a parasite or commensal, tapping a host's blood and filtering out toxins.  -**Assessment:** Only nearby source of drinkable water.

This is most likely a bug.
