Twilight Sparkle, as hungry for knowledge as the great unicorn mage Starswirl the Bearded, has created a portal to the multiverse, where endless wisdom awaits her. Excited, proud, and perhaps too tired to be thinking straight, Twilight jumps right into adventure! What does she find? Well, she certainly isn't too big for her britches... compared to the giant horses she meets, how could she be? Suddenly feeling pretty small, Twilight finds herself a foal for a night until she can find a way to prove she's intelligent. Well, it could be worse; at least these Big Horses make some pretty good parents.
