Sea Otter



Favorite Gup



Keith Wickham

Shellington Sea Otter is the Octopod's marine biologist with a Scottish accent. He's a cute, nerdy sea otter who loves doing field research and working in his lab. He's easily distracted by rare plants and animals and often gets into trouble because of this, but his knowledge of the ocean is a big help in Octonaut missions.

Though he may be knowledgeable about marine life, Shellington is a terrible driver and has crashed the GUP-D twice and the GUP-E once. But, he will probably soon learn how to drive a GUP properly. His favorite Gup is the Gup C. When out on missions, he's usually sitting in the back or in the passenger seat, and for good reason.

Some of his talents include playing the harp, playing the piano (possibly), golfing, drawing, sleeping during missions, crashing the GUPs, and being humorous.

Just like Tweak, Professor Inkling and Tunip and the vegimals, Shellington appears to sleep where he works so his room doubles as the ship's lab. The shelves are filled with many different samples that he has collected while out on missions. This is where he is usually found, viewing samples through his microscope. When not in his room, he is also found in his seat up in the HQ where he assists Dashi with the ship's computers.

In both the original UK version of the show and the US one, Shellington has a Scottish accent.

Shellington has a sister named Pearl and a nephew named Periwinkle. Oddly, unlike his sister and nephew, he wears a helmet while diving, like the other Octonauts. Also, he's allergic to red sea urchins- a delicacy for sea otters.

Shellington happy

His fur is brown, with some spiky looking fur hanging down over his forehead, and a sand colored face. He's normally seen wearing a waterproof satchel, and wears a pair of blue boots and a blue hat with the Octonauts' logo on it. He's usually seen holding his favorite magnifying glass as well. Of all the Octonauts, he is the only one, other than Peso, who has a mouth that doesn't have a peanut-shaped "mustache" as some people call it. His pajama outfit includes green plaid slippers and a striped green nightcap with a fluffy pom-pom on the end.
