Stowaway

Stowaways are stationary predators exclusive to the Downpour DLC. They reside in dim underground areas, and utilize camouflage to ambush prey.

Appearance
The body is relatively small, and mimics the texture and appearance of pipes its attached to. Before triggered, the Stowaway's body is shrunken into their perch on the ceiling, with long grey tendrils reaching down to the floor, acting as sensors. When triggered, the body suddenly juts out and opens its maw, revealing five jagged faded pink teeth. Three long pinkish grey tentacles drop down from inside the mouth, almost quadruple the length of the main body. These tentacles each have a jagged hook at the end.

Combat
Fighting against Stowaways can be very tricky, as they're near invisible ambush predators with a fast attack, however, you can dispatch a Stowaway before its ambush is activated. Its main body has a hit box. It can easily be killed using a from a distance. Hitting a Stowaway's main body with reveals its exact location, making it easier to avoid or kill. If the ambush attack is activated and successful, things get significantly more complicated. The Stowaway's three tentacles constantly attack a creature, keeping it in a stunned state, until it starts to pull its prey towards its mouth. Since its tentacles have hit boxes (much like and ), a  thrown into a tentacle at the opportune moment causes the Stowaway to release its grasp. s cause all Stowaways in the area to release their tentacles, before quickly retracting them. Cherrybombs also cause Stowaways to release everything in their grasp.

Similar to other Arthropods, s can kill Stowaways.

Evasion
Evading a Stowaway is a much simpler task - as the ambush attack is only initiated if a creature is touching its sensory tendrils for a prolonged period of time, quickly passing underneath a Stowaway is enough to evade it. In the case that its ambush is initiated, its tendrils can be avoided by quickly running to one side of it until the is out of the Stowaway's reach. Creatures can be thrown or lured into the tendrils to activate them prematurely, since the Stowaway only focuses on one creature at a time, this can be used for safe passage while it's distracted.

Camouflage
Stowaways excel at blending into their environment, being almost completely invisible except for the sensory tendrils they let down to catch food. This is partially due to the environments and regions they reside in, being dark and filled with roots, pipes, and dead vegetation to mask themselves around. They sink slightly into the platform when in wait of prey to cover less surface area and be less visible, and stay that way until their sensors are triggered.

Predation
Stowaways predate in a unique and effective way, when the sensory tendrils are set off, they extends out from their perch in the ceiling to get closer to their prey. Then, using the three hooked tentacles they are sporting, they periodically stuns their prey, making sure it's immobilized and doesn't have any way to fight back. Stowaways then bring the food up to their mouth, swallow it, and resume their place stuck snugly in a ceiling. When prey moves around while Stowaways are in an active state, they follow it with its mouth to ensure its not only closer to being eaten, but so they can effectively launch their tentacles out.

Variants & attributes
The tentacle and tendril amounts never vary, but the teeth amount can, ranging from 4-6. The color of the body isn't variable, a brown-grey with darker grey stripes. The teeth can take on a shade of deep grey to light pink, and the tentacles have a gradient also ranging from grey to pink.
