Different of book and film

   First in the film it was happy ending, because the fat man helped to prepare the funereal, so Ashmol could organize funereal and prepared funereal with his mom and dad. Also many people came to funereal and said sorry to Kellyanne for Pobby and Dingan. However in the book it was very sad story, because at first the fat man did not give back the opal to Ashmol. This was the beginning of sad story, and Kellyanne dead at last. Also old Sid did not show up in the funereal, so both film and book have different ending story, happy and bad ending.
