In Book 8, the Ninja Meerkats receive strange reports from the Australian outback. They fly down under to investigate and discover strange goings-on in the desert.

With boxing kangaroos and killer koalas—not to mention the Ringmaster's crew of deadly circus goons—the Ninja Meerkats are on deadly desert mission.
