Mia and Me (2012)

Season 1: Episode 10

Jealous of Mia's ability to jump to Centopia, Vincent wants to give it a go himself. Though Mia reluctantly lets him try, she ends up transported there instead. And it's a good thing, because someone needs to stop the unicorns from visiting the Blossom Tree for their annual feast - they'd be too exposed to danger. When the stubborn unicorns refuse to listen, the elves must enlist the help of the reclusive but awesomely powerful Earth Unicorn.
