Thylacine is an extinct species of marsupial from Australia. Tani Tiger and Tiny Tiger are the last of their kind, but Derik is became more dangerous than ever.
- Despite them being extinct, there have been recent sightings of thylacines over the years which could mean that there are still more out there, hiding from being killed. The humans do realized their mistakes and try to reverse what they've done to bring these magnificent creatures back from extinction. They can clone them, find footprints that are similar to the known thylacine tracks, and take pictures to show evidence of them.
