Tunnels

Blornvid has never seen it but Skeeve recognizes it is a simple organism that grows near mineral rich waters but normally it does not grow to this extent without another source of energy such as a thermal vent or dead animals. Though not deadly it has a slight numbing effect that makes those that eat or drink it thirsty. As animals drink the water it is lapped up and causes the animals to keep drinking the water thereby poisoning themselves and dying nearby.

Skeeve recalls the slime is safe as long as it is not ingested or rubber into an open wound. As you look around you see something reflect the torchlight at the bottom of the pool. The thin layer of slime on the surface obscures it but the spear to be a couple manufactured items

The rope shoots into the water and wraps around something. It seems about as effective as shooting a crossbow bolt into water. It is only effective at short depths. Luckily the pool is not that deep. However . . . As you pull on the rope the entire area around the pool explodes into motion startling all of you!

Two large pseudopod stretch out and slam into Skeeve and Raggy

Skeeve already waryn jumps out of the way but Raggy is slammed by the protrusion and tendrils wrap around grasping him tightly.
1 damage to Raggy who is also stuck to the limb

Vlax fires an arrow that sinks into the rising creature as Skeeve pulls on the rope and ends up extracting an crossbow out of the oddly thick and vicious fluid that is now clearly not water. Raggy pulls his knife, slashing at the beast to free himself by slicing deeply into the creatures arm(?). Ro snarls and sinks its teeth into the flesh that looks like stone but is clearly not. Then with a Whirl of his massive ax Blronvid severs the thick protrusion, freeing Raggy. Your attacks look to have severely wounded the creature.

The beast exudes a bubbling hissing noise of pain and anger as it rears up, the pool becoming a mouth and a new arm forming to attack again. As it lunges the massive maw closes on Raggy (1 damage) while the two arms wave about with one striking Blornvid solidly (1 damage)
