SPOILERS ABOUT HARRY POTTER

I read chapter 3 yesterday of Harry Potter and the Prisoner of Azkaban and it's about The Knight Bus. There was no jamican shrunken head on the bus like there is in the movie! Why on earth would Alfonso Cuarón add that to the movie!? That was probably the most annoying thing in all of the trilogy (especially on the special features). DAMN YOU Alfonso Cuarón for that move! mad
