Benevolent Squid

Quotes from a thread on the Twisting the Hellmouth forums

As far as I know the only three people from the wizarding world who knew where Harry had been stashed was DD

And the squid (whose name I can't remember) who was watching over Harry while he grew up. Who one would think might have noticed how Harry was treated and reported back to Dumbledore.

My reaction:

Now I want to write a crossover which has Harry living underwater with evil fishy guardians, being watched over by a benevolent squid. Maybe a spongebob Squarepants crossover?

Except that I really don't want to write this - too many other things to do, and I don't know Spongebob Squarepants at all well. So if anyone feels like taking up the challenge...
