The adventurous Sienna accidentally finds an entrance to a mystical world that is inhabited by magical creatures such as Mixies and Mixlings. To get home she must embark on a journey through enchanted realms to find a magical castle.

Ep 101 - When poking around Lolo's attic, Sienna finds a prism that unlocks a glittering pathway to a magical land called Mixia. There's only one catch - the path disappears, and she becomes trapped there. After coming across a Spell Book, a wand, and a cauldron, she casts a spell that creates a Mixie, Carrot. He informs her that the magic in Mixia has gone haywire and that to get home, she will have to travel to the Castle. But Carrot's not great with directions, so Sienna summons the Mixlings Geckler, Pixly, and Luggle along the way. But the path they take ends up flipping the whole world upside down. They'll have to work together to flip it right side up.
