From their "Octopod" home base, a team of undersea explorers is always ready to dive into action to explore new underwater worlds, rescue amazing sea creatures and protect the ocean. The group is led by Captain Barnacles the bear, and also includes Kwazii the kitten, Peso the penguin, Dr. Shellington the sea otter, Dashi the dog, Tweak the bunny, Professor Inkling the octopus and Tunip the `vegimal' (part vegetable, part animal). The animated series, geared toward preschoolers, is based on a book series of the same name.
