Okay but imagine this : Newt Scamander being the one who put the squid in the lake (not Dumbledore) when he was just a tiny baby squid like "Be free my friend !!!" and then it grows up into a GIANT F*CKING SQUID
Newt is called back to Hogwarts urgently and ppl are like “HOW THE FUCK DO WE DEAL WITH THIS” and he’s like “no no leave him he ain’t hurting anybody he’s a vegan i promise look at him he’s adorable i’m gonna call him Sasha “ and ???? ppl don’t ??? get it but okay i guess and that’s the story of how Hogwarts got a giant, inoffensive squid in the lake. the end. Hagrid will take good care of it.
