There is a small uncharted island just off the coast of Australia where these creatures, called TasaBobs, still thrive. The island is home to a village called Scatawompus where a small tribe of vegetarian aborigines have domesticated this largest carnivorous marsupial on the planet and keep them as house-pets and guard animals. The legend says that these beautiful and yet still dangerous TasaBobs are a cross between the native Sarcophilus Harrisii and European cats called Pixi-Bobs that came across the Indian ocean aboard the original Penal Colony ships around the year 1789.
Unfortunately, the only way to acquire one of these beauties is to sell all your belongings and sail up to the edge of the island in a dingy while holding a large white flag and singing a chant only the natives know the words to. If they throw you a line, then you are accepted into their family and get to live among them, sharing the joy of a truly peaceful and safe place while raising a TasaBob of your own. If not, the natives make a nice stew, for their pets.
Bon Voyage!
