Sue Ellen's Lost Diary

Summary
Sue Ellen loses her diary in the library. Muffy, Francine, Binky, and Arthur find it, wondering what's inside and whether to open it or return it unread.

Trivia

 * Sue Ellen's comment at the end, "I said some pretty nice things about you!", is a reference to Arthur's original crush on her in the books.
 * During Francine's imagination of what Sue Ellen wrote in her diary, the date is day 162, once translated the date is June 11.
 * During Muffy's fantasy, she plays as Princess Millicenta who wears a blue princess dress and long curly hair. When Millicenta comes out of her castle, she wears a single braid, but still wearing a princess dress. However, in Arthur's New Friend and Arthur's Perfect Christmas, Muffy stills wears a princess dress, but double braids just like in her original appearance.
 * At the end, when Sue Ellen leaves Arthur blushing the background changes.
