Tailypo

A nocturnal Appalachian revenant defined less by what it is and more by what was taken from it. The Tailypo is a shape-shifting forest creature whose presence is marked by a single fixation: the recovery of its severed tail.

Location: Tennessee mountains

An old man living alone in the mountains was cooking stew when this creature came in through a crack. He caught it and cut off its tail for his supper. That night, he heard scratching and a voice calling 'Tailypo, tailypo, give me my tailypo.' Each night it came back, getting closer. By the third night, it was in his cabin, on his bed. His dogs tried to chase it but never could catch it. Some say the old man was never seen again.

Re:Tailypo - Case TAI-007
Tailypo incidents are consistently associated with isolated dwellings, food scarcity, and the removal or consumption of a bodily part belonging to the entity. Field records indicate the creature demonstrates memory, persistence, and target-specific behavior rather than generalized predation. Once an initial offense has occurred, Tailypo activity escalates in predictable stages: auditory contact, perimeter disturbance, removal of domestic animals, and eventual forced entry. Interruption of this sequence has not been documented. Field agents are advised that Tailypo vocalizations should not be answered or acknowledged. Attempts to secure a dwelling or confront the entity have resulted in loss of animals and, in several cases, loss of the primary resident. Recovery of remains is uncommon. The Bureau strongly advises against the harvesting, consumption, or retention of unidentified fauna under any circumstances. Relocation is recommended at the first confirmed vocal contact.
