Courageous feline Pero once wagered with the deceitful multimillionaire Grumon that he could circumnavigate the globe in eighty days. The bet carried great risk: if Pero succeeded, Grumon would hand over his entire wealth; if he failed, Pero would be bound to serve Grumon forever. With loyal companions Kato the giant and daring Small Mouse, Pero set off on his journey. Grumon employed every trick to stop them from reaching the finish line.
