Octonauts

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. The Octonauts must evacuate sea creatures before an underwater volcano erupts, but there's one creature that won't budge: a slow moving, gelatinous Blobfish.
