Blessed with a toxic skin, vicious claws and an all-but-insatiable hunger for all manner of inorganic matter, the diminutive Pting can be a menace to interstellar travellers as the Thirteenth Doctor found during The Tsuranga Conundrum. Pting are believed to have been impossible to kill, and could even survive in the vacuum of space. They could even eat a bomb and barely be affected when it detonated other than temporarily sating its rapacious hunger.
