While playing with Charlie, Harry keeps wanting to go first and Nana warns him that he's not using his best manners. In fact, it seems that Charlie doesn't want to play with Harry anymore because of his behavior. Nana decides to teach Harry about manners by giving him a book all about knights. Harry decides to go play knights in Dino World. Rather than learning all of the rules of knighthood, though, he decides to simply go on a quest to slay a dragon. When things don't go quite as planned, he finds that maybe manners are important after all.
