Mia and Me season 1 episode 16
Episode title: The Unicorn Trap
Mia's class is on a camping trip where she's unfortunately been grouped with Violetta and her gang. When the prissy Violetta is completely unable to start a campfire, her whole group begins to starve. Mia flees to Centopia, where Panthea is plotting a way to capture the golden-horned Onchao. Being isolated from his own kind makes him particularly lonely, so Panthea and Gargona devise a foolproof plan: building a kind of "Trojan unicorn" to lure him in.
