Real-life thylacines.

The Thylacine or Tasmanian tiger is a species of meat-eating marsupial native to Tasmania. They are the species that represent Ty, Sly, and their families.

Since the late 1800's, a bounty was placed on thylacines after they were blamed for attacking sheep. In 1909, the bounty was ended, and the thylacine became very rare. The species was sought by zoos around the world. The last wild thylacine was killed in 1930, and the last known thylacine (named Benjamin) died in the Hobart Zoo in 1936.

As of today, the thylacine is officially declared extinct. But since the last one died, there have been hundreds of sightings reported in Tasmania and Australia. Many people believe that the thylacine survived extinction and may be rediscovered in a matter of time. However, concrete proof is yet to be found.

There have also been plans by scientists to clone thylacines back to life using the DNA of frozen thylacine embryos.
