Animated deep sea adventure series. Captain Barnacles and his intrepid band of explorers roam the oceans in search of adventure and fun. Whether it's a perilous voyage to the bottom of the sea or the piratey pursuit of a giant squid, the Octonauts leap into action and always prove that eight heads are better than one. When Kwazii's Gup-B breaks down in a storm, not even brave Captain Barnacles can save him alone. Fortunately, a chain of reef lobsters lends a hand - and some claws.
