Captain of the Octonauts and Researcher
Barnacles Bear is the captain of the Octonauts and one of the bravest polar bears you will ever meet. He is one of the strongest of the staff. Always the first to rush in and help when there's a problem, the crew has great respect for him.
Along with being the captain, Barnacles is also the strongest member of the crew and he's demonstrated that in a number of different episodes. He's also one of the most level-headed crew members, often dismissing his crew mate Kwazii's outlandish stories about sea monsters and ghosts.
It's also been revealed that he rather fancies playing the accordion. To his mind, he's quite good at it, but Kwazii, who has the misfortune of living in the same pod, doubts it, as seen in "Octonauts and the Orcas". So far the only ones to appreciate the music have been a pod of Orcas. He is also a oceanographer and a map finder.
In both UK and US version Captain Barnacles has the same accent.
All white fur and a blue uniform with a matching hat. He's also always seen wearing his favorite compass on his belt. His earlobes are white, though the insides are bright blue.
- Exercise attire (in books)
- Deep Sea Suit
- Pajamas (many times in the show)
- Snow Suit (despite being a cold adapted animal)
Captain Barnacles sounds of the Octo Alert to gather the Octonauts to the main deck to help an underwater creature. He does not usually sound the Octo Alert himself, he sends the person closest to him to do it, or the one that has a problem. When he calls for the launch bay he runs down the hallways and shoots down chutes with Kwazii and Peso. In one of the episodes, he is seen weightlifting, which gives him his strength. He has a habit of saying "Octonauts, to the..." when he hears the Octo-Alert, even if he wasn't the one who sounded it (episodes "The Kelp Forest Rescue", "The Crafty Cuttlefish", "The Mantis Shrimp", etc.).
