Can bạn name this movie for me?

what i can remember is that a weird/old travelling man comes to the door selling things - including staffs (walking stick). there is one with a con nhện, nhện on the hàng đầu, đầu trang and one with a crescent moon. The boy steals money from his mother to buy the one with the spider. that night he wakes up to thousands of spiders in his room. I can't remember anything else except that if he bought the one with a moon then things would be a lot worse than spiders. I think that is just the beginning of the film
