this unusual creature was bioengineered by the Yuuzhan Vong. Resembling a blob of protoplasm, the ooglith masquer could be draped over the head and torso of a Yuuzhan Vong and become a living mask. The masquer would extend thousands of tiny grappling tendrils into the pores of the Yuuzhan Ving skin, latching the masquer's body directly to that of its "host." Externally, the masquer created the appearance of another species, allowing the Yuuzhan Vong to walk among another species without being detected as wearing a prosthetic device. The ooglith masquer had to be trained to remain in a certain form while attached to the Yuuzhan Vong's face. At the push of a sensitive point on the ooglith masquer's body, the creature retracted its tendrils and peeled away from the Yuuzhan Vong's face, once again becoming a shapeless entity and returning to its contained.
