Vahni Vahltupali were tall, slender and vaguely humanoid, having two legs, a narrow torso, two tentacles in place of arms, and a bulbous head-like projection ringed by a complex ocular organ. They possessed neither vocal nor auditory organs, but were able to change the colour and texture of their flesh akin to an Earth octopus. Their skeleton was firm but malleable, and many-jointed, enabling dramatic contortions.
