Treghrum

The Treghrum is an unusual predator found commonly throughout the desert.

Anatomy
The Treghrum is a rare predator specialized in the use of aggressive mimicry. This multi-legged creature can fold its body to closely resemble a Trebhum; in this way, the imposter will infiltrate a group, acting as one of its members until it finds the right moment to strike. However, Treghrum are not truly intelligent and cannot lead a group. If the creature's deception is exposed, spraying it with water will cause it to flee by burrowing into the sand. If it perceives the group as vulnerable, however, it may seize one of its members.

Behaviour
The Treghrum impersonates as a Trebhum mindlessly wandering throughout the desert. They have yellow snake-like eyes, but real Trebhum are only found in eggs, in a weakened state, or in Trebhum Houses.

They can also be uncovered by spraying them with water, making them retreat back into the sand.
