"The little sister": Mia would like to spend her summer holidays on a horse farm in the Tyrolean Alps, but her room is no longer available. So she starts looking for accommodation, meeting Sara. Back in Centopia, Mia experiences how Onchao's mother Lyria gives birth to the unicorn foal "Kyara". Gargona also sees the birth of the foal and immediately reports it to Lord Drakon. "The poisonous souvenir": Mia has spent the night in the stable when Sara's mother comes in with breakfast and informs her that she will bring Peppino back to the riding stable. In Centopia, Lord Drakon Gargona introduces Dax and his four hoppers. A plant around Panthea's old palace is cursed and becomes the evil Night Vine, which takes possession of Centopia and thus also of the elves and the unicorns.
