Tentacle are creatures native to the planet of Na Pali, appearing in Unreal. They consist of a base with three tentacles protruding from it and a red mouth at its centre. This base is attached to the ceiling of caves or buildings by a number of suckers. When killed, the Tentacle's suckers release their grip from the ceiling, dropping the creature to the ground. Some Tentacles will, in a last-ditch attack, attempt to throw themselves at their surviving victim, though such moments are rare and, fortunately, only serve to shock the victim, rather than hurt it.
Tentacles are fragile creatures, relying on stealth to take down prey. When dormant, the creature's tentacles will furl up towards the base in an attempt to blend with their natural environment, and they will usually hide themselves in dark corners or just after the entrance of a larger room to avoid notice. They stay in this state until prey reaches a certain distance. When prey reaches this distance, they will unfurl, growling and firing small thorns from the larger central tentacle until the prey is dead, and striking it away if it gets too close.
