At first, I was unimpressed with the start of the story. But I quickly got pulled in when the witch and the toads appeared. The story gives me the children's story kind of feel, reminding me of stories like Goldilocks and the Three Bears, or Jack and the Beanstalk.
The moral of the story is to do things one step at a time. And not to bite off more than you can chew. And not to take shortcuts when visiting your grandparents ;p
