Ember decided to take Garble to Ponyvillie to check on his sister, due to him not knowing where Ponyville is. Though Principle Starlight isn't there at the moment and Garble decides to look for her in Twilight's castle. Spike and Smolder try to stop him as no one's allowed in there without permission.

Things get worse as Garble and Ember come across a certain mirror, which they turn on. One thing leads to another and they get transported to a new world, with new bodies.
