Fox ears au by fanfic_obsessed23
Fandoms: The Octonauts (Cartoon), Harry Potter - J. K. Rowling
06 Jan 2026
Tags
Summary
What starts as a normal check up of the octopod turns into something that seperates
Note: In my headcanon Barnacles is from an indigenous Inuit tribe, a FICTIONAL Tribe of polar bears because British Barnacles is just wasted potential in my opinion
Slight Warning; Because of Barnacles's good hearing I gave him a sort of dissociative disorder without really realizing it, or meaning to, he kind of starts using words like “won't” or “octo agen’”, basically he starts using contraction words when the noise gets too loud and kind of spaces out
Not really a cross over, the bag Barnacles has and the board are just magic and a scene later will include magic from the Harry Potter world, but that's it; for now at least

Summary
The entirety of existence itself seems to swirl relentlessly around him, the outside of his physical body mixing with the sensations within him. Years of diligent and dedicated self-improvement and growth collapsing in on itself with no fanfare.
He’s frozen.
Out of the corner of his eye, back in the mirror he sees it. An eye, all too familiar staring at him, through him.
That frightened child.
