Ok so there's this movie I used to watch and it's about a boy and he moves with his grandma and his grandma tells him about witches and how they have square feet. There's one scene where a boy is up in the tree house and a Woman comes by with a snake and she tries to hypnotize him or something. He is like 8 or so in the movie and there's another scene where the witches all gather at this convention thing and the boy (main character) is hiding behind a piano on stage... can anyone help me with the name of this movie please! Thank you
