“OCTOBER arrived, spreading a damp chill over the grounds and into the castle. Madam Pomfrey, the nurse, was kept busy by a sudden spate of colds among the staff and students. Raindrops the size of bullets thundered on the castle windows for days on end; the lake rose, the flower beds turned into muddy streams, and Hagrid’s pumpkins swelled to the size of garden sheds.”
concept: instead of hedwig, Harry goes into the pet store and this little snake in the back of the store talks to him, obviously gets his attention more than the other animals, and harry feels sorry for it so he takes it home. Then the snake helps Harry throughout his years at hogwarts as harry carries it wrapped around his hand all like “pssssst, haaarryyy, the dark lord isss coming sss” or just petty shit like “haaaarrryy, now is the time, assskkk out cho chaaannngg”
The snake getting really agitated in second year and Harry like ‘Aw, what’s wrong little friend?’
And snake’s like ‘Nah don’t worry it’s cool, it’s just that big fuck-off snake in the pipes that keeps making you think you’re hearing things—it’s like, ten thousand foot long, and I’m a corn snake, so you know. Bit intimidating.’
Third year he eats Scabbers and saves them all a lot of time
