he Octonauts is a British children's television series, produced by Silvergate Media for Cbeebies and animated by Brown Bag Films. The TV series is based on American children's books written by Vicki Wong and Michael C. Murphy of Meomi Design Inc.

The Octonauts follows an underwater exploring crew made up of stylized anthropomorphic animals, a team of eight adventurers who live in an undersea base, the Octopod, from where they go on undersea adventures with the help of a fleet of aquatic vehicles.

The subject matter is reminiscent of Star Trek and Thunderbirds blended with Jacques Cousteau. Although it is science fiction as regards its technology, the exotic creatures and locations that the crew encounter are real marine animals in their natural habitats.

My nephew who is 2 loves that show I was wondering if there was an address please

Thanks
