Kwazii

Kwazii is a daredevil cat with a mysterious pirate past. He loves storms, driving fast and general excitement, traveling and exploring new, exotic places. He can sometimes take the place of Captain Barnacles if he's absent or "doing something at the moment".

Kwazii is one of the best drivers on the Octopod. As befits a pirate Kwazii believes in many different kinds of sea monsters and legendary beasts, in fact he believes in so many that he's also considered the crew's cryptozoologist instead of just a lieutenant. Often times he seems to try and scare his crewmate Peso the most with his spooky stories. He's hot blooded and considered to be one of the bravest of the Octonauts, but it was revealed that he does have a fear of spiders and has a soft heart for cute small animals.

He makes references to his pirate days very often and evenhis room on the Octopod has a pirate theme to it.

In both the original UK version and the US version of the show, Kwazii speaks with a typical sea ferrying dialect.

He has also found out that his grandfather is still alive and looked for the hidden golden city with him in the episode "The Octonauts and The Amazon Adventure".
