Mia and Me (2012)

S1E16 The Unicorn Trap

During a school camping expedition, Mia finds herself teamed up with the snobbish Violetta and her friends. When Violetta fails miserably at lighting a campfire, her entire crew faces hunger. In a bid to escape, Mia transports herself to Centopia, where she discovers Panthea scheming to ensnare the golden-horned Onchao. Feeling isolated from his fellow unicorns, Onchao's loneliness makes him an easy target. Panthea and Gargona concoct a clever scheme, creating a "Trojan unicorn" to entice him into their trap.
