The screenwriter has changed the timimg of the story from August to the beginning of summer. The metaphor about the Ferris wheel hanging at the top like August hangs at the top of the year no longer works! Also, Winnie is aged by about 6 years, making her closer to 16 than 10. Finally, her parents play a much more prominent role than they do in the book. Her parents are characterized as bossy, overprotective, and downright mean! It does make it more obvious why Winnie runs away- in the novel we only hear her grandmother and mother in the background, so to speak. Here they are much more in the forefront of the tale. Most importantly, the ever-present and symbolic toad is barely mentioned in the film. It does appear in a few scenes, but is never explained or pointed out.
