Captain Barnacles x Oc. this takes place in the episodes of S3 and S4. Desclaimer: I own nothing of The Octonauts.

Shellington is tired of wait in front of the bathroom that they have. So Tweak made to restroom one is for "Men's" and one is for "Women's" but Barnacles and Shellington have a fear of public restroom.

Dashi faints than wakes up to find herself in Tweak's bed. What's gonna happen?

It's when barnacles noticed that there was something very strange about peso

After Captain Barnacles and Kwazii get into a fight Barnacles leaves Kwazii alone on a island swearing up and down that he'll not come back for him. Will the Captain find it in his heart to forgive Kwazii ... Or will he leave Kwazii alone forever. My OC included. Completely for fun. XP

Desperate to leave the Octonauts, Captain Barnicles swam to the surface, stole the identity of Hagrid, and kidnapped Harry. Over time, Barney develops friendships, doing whatever he can to keep them. But has he gone too far? Find out in this exhilarating adventure.

Barnacles goes to the human world to help some old friends of his, and they have an uncanny resemblance to his crew.

It's been a long few weeks for the Octonauts, and Inking can't help but think back to when he first created the crew. Was it worth it, or should he have never tried? What would have happened if he had never been born? These questions are answered when he is taken on a mysterious journey where he sees exactly what his world would be like without him.

(Warning: Old story and very cringy! I'm so sorry) I was looking through Wattpad and I noticed that there was was no Shellington x reader stories so I decided to make one. In this one, you are Tweaks twin sister. You wear glasses to tell the difference between the two of you. As a new recruitment of the team, you help your sister with the mechanics of the Octopod(fixing the ship, making new gups, etc.) What happens when a certain member of the team catches your attention? Octonauts doesn't belong to me. You belong to you. The story plot is mine.

Here's the sequel to Driving Lessons! Dashi and Shellington are now happily together, and Shellington has learnt to drive better with Dashi's help. Now Kwazii is under the firing line - with a certain engineer. Will Kwazii learn to consider Tweak's feelings instead of crashing Gups all the time?
