The "Failed Experiment" is an anthropomorphic slime woman composed of a viscous, glossy, purple substance. She features long, dripping strands of slime that obscure her face, two antennae or ear-like appendages on her head, and thick tentacles serving as her lower body. Her name implies she is the result of a botched biological experiment conducted in the laboratories of the Teleena aliens. Despite her status as a "failed experiment," she shares the instinctive trait common to the other female alien inhabitants: an insatiable hunger for intruders. If the Failed Experiment captures You, it triggers special, hand-animated "slime hug" and absorption sequences in which the creature envelops You within its massive, gelatinous belly to expand its own Body.
