Differences between the book and the cartoon

 * In the book, Sue Ellen's diary was red with "My Diary," "Private," and "Do not open," on it. In the cartoon it was yellow with "Private" written on it in various languages.
 * In the book, Sue Ellen lost her diary because it slipped out from all the other books on the stack she was carrying, and found it missing when she retraced her footsteps to retrieve it. In the cartoon, she simply forgot the diary on the table, and it vanished when she returned to get it.
