Join the animated adventure heroes as they dive into action whenever there is trouble under the sea.


The Octonauts follows a team of animated adventure heroes who dive into action whenever there is trouble under the sea. In a fleet of aquatic vehicles, they rescue amazing sea creatures, explore incredible new underwater worlds, and often save the day before returning safely to their home base, the Octopod.

Buoyed by the companionship of three leading characters - Captain Barnacles Bear, Lieutenant Kwazii Cat, and Medic Peso Penguin - the Octonauts are always ready to embark on an exciting new mission!

Based on the richly imaginative books by award-winning design team, Meomi, the TV series combines elements of classic team adventure with stunning CGI animation to transport little ones into a magical world under the sea.

The show will arouse their curiosity and feed their imagination, answering questions in a journey of discovery through the world's oceans.

Read about the characters

Captain Barnacles Bear

Captain Barnacles Bear is the heroic leader and strategic thinker of the Octonauts. With the Octo-compass (a multipurpose smartphone) strapped to his belt, he's the first to rush into unchartered waters at the first sign of trouble.

Lieutenant Kwazii

Lieutenant Kwazii is a daredevil orange cat with a mysterious pirate past. Sporting his eye patch and wielding his spyglass, he's an explorer at heart. As a pirate, he was motivated more by his love of adventure than his love of treasure


Peso is the medic of the Octonauts. He's the youngest member of the crew and the most likely to take Kwazii's tall tales seriously. He's not too fond of scary situations, but if someone is hurt or in trouble he can be the bravest Octonaut of all.
