Cassie, the Green-eyed Dragon - Everyone rushes to the School in the Sky to see Cassie's big surprise - her little brother, Finn! She has brought him to school so that she can tell all her friends how adorable her baby brother is. As she is speaking, she can't help but notice all the attention this cute tiny tyke is taking away from her. When Cassie simply can't take it anymore, she blurts out: "I wish I'd never brought him!" Quetzal speaks with Cassie and she admits that she's jealous. Quetzal assures her that this is very normal among brothers and sisters. Cassie feels better, but now Finn is hungry and no one seems to be able to feed him. Thank heavens for big sisters! Cassie knows some tricks that coax Finn into eating his snack, saving the day. Hello, Miss Tipps - When Quetzal is called away for the day, the young dragons and their friends face a substitute teacher, Miss Tipps, for the first time. This change in routine upsets Lorca. He has been looking forward to hearing Quetzal tell the story of Prince Griffin, and is disappointed as Miss Tipps takes the students on a field trip, has music at a different time with strange instruments, and offers the class an unfamiliar treat at snack time. By the end of the day, Lorca is surprised when Miss Tipps concludes the day by reading the story of Prince Griffin. To the students' (and Lorca's) delight, all of the activities they did that day that strayed from their routine were actually parts of the story of Prince Griffin. Sometimes a little change can be... a beautiful thing!
