Ducky's relationship with her brother Spike becomes rambunctious and turbulent when he repeatedly keeps her awake at night with his snoring and after he ate her tree stars (which their mother packed specifically for her on their first day of school). She tells Cera about her feelings, and confides that she does not know how to express them; Cera agrees to teach her. Meanwhile, the children are attending a school in which they are taught by an old ''Pachyrhinosaurus'' named Mr. Thicknose, who professes to have been everywhere and seen everything. Littlefoot eagerly questions the topics they cover, to the old dinosaur's irritation. Eventually, Mr. Thicknose complains to Grandpa Longneck about Littlefoot's behavior. Grandpa, knowing Littlefoot meant no harm, explains to him why he must be more respectful to Mr. Thicknose.
