Plot

Petrie is having a difficult time preparing for "The Day of the Flyers", an important day for all of the flying residents of the Great Valley, when all of the young flyers must participate in a very precise flying exhibition to prove that they are ready to fly with the adults. Always a nervous flyer, Petrie has even more trouble flying with his siblings in precise group formations -- he's more of an independent, free-style flier. At the same time, a strange newcomer to the Great Valley has Littlefoot and his friends trying to help figure out just exactly what he is. Named Guido, a Feathered Flyer, he's the strangest looking creature any of the Great Valley creatures has ever seen, especially since he's covered with feathers, and has never seen another like himself. Cera is having her own troubles, as her grumpy father and his new mate, Tria, get ready to welcome a hatchling to the family. The hatchling's name is Tricia and Cera begins to slowly bond with her new sister.
