Calico jack and Kwazii are both conspiracy theorists , they mainly just believe in relatively tame stuff about aliens and ghosts but calico jack has some more out there beliefs about the government.They often sit together and watch conspiracy theorie YouTube documentaries together.
Calico jack moved in with kwazii when he was found and gets very lonely when kwazii is away for long periods of time for work, but he always pretends that he likes having the house to himself , kwazii knows that it’s just an act cuz of how clingy and doting calico jack is when he gets home.
Sometimes when they fight (very rarely do they fight) kwazii threatens to put calico jack in a care home.
They watch blue planet together.
When Peso comes over for dinner calico jack always attempts to make a traditional chilean dish.

----------------------------
A Barnacle's headcanon (I have, since y'all want more Barnacle's lore of my AU). Is Barnacle's used to have a family way before he joined the octonauts. A loving mate with a cub. But they were lost to him. It sent him into a deep dark depressive state and eventually uncontrollable anger and aggression believing it was all his fault, but now learning new lessons and now being a gentle bear, he joined the octonauts and now had started a new family with shellington and had his pubs. He vows to himself to always protect them and be there when in danger.
