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. Who else could be behind it but that top-hatted menace, the Ringmaster? He is building missiles to take control of the world. 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.
