Ty is a Tasmanian Tiger who was raised by a family of Bilbies from a very young age, and has only vague memories of his family and friends. He has always believed that his relatives died long ago, leaving him as the only surviving Tasmanian Tiger. During a chance meeting with the Mystical Bunyip Elder he discovers that his fellow Tasmanian Tigers are still alive, but are trapped in the otherworldly realm of the Dreamtime. He also learns that deep in the Australian outback there exists a rocky outcrop with five sockets. When five magic Talismans are placed in the sockets, the portal to the Dreamtime will open. Unfortunately, these Talismans have been lost and an evil cassowary by the name of Boss Cass is trying to find them. Now Ty is on a quest to recover the Talismans before Boss Cass. If Ty is successful in defeating Boss Cass and his evil minions and activating the portal, the Tasmanian Tigers will be freed and able to populate the Earth once more.
