Mia and Mario continue to look for ways to earn enough money to save Renzo's farm, and discover something that just might be the solution: An upcoming horse-riding competition. However, before they can register Sapphrie, they need to get the documents relating to him from Contessa Di Nola. Franca promises to see if she can help them obtain the documents.
In Centopia, one of the animals, Scrobbit, seems to be feeling down, so Mia and the others try to cheer him up. Scrobbit later manages to get a hold of one of the two rings from Ono's crown that the elves had retrieved and manages to get into Polytheus' island. Mia and her friends must try to figure out why Scrobbit is acting so strangely, and help Polytheus to get Scrobbit away from his treasure horde.
