The Octonauts expand their exploration beyond the sea — and onto land! With new rides and new friends, they'll protect any habitats and animals at risk.

A street-smart dog and a pampered cat join forces to lead a pack of unlikely heroes when their city is seized by its evil mayor — and his robot army.

The Octonauts embark on an underwater adventure, navigating a set of challenging caves to help a small octopus friend return home to the Caribbean Sea.
