Disney Highschool

A school for Disney/DreamWorks girls. A separate school for Disney/DreamWorks boys. No one is allowed to go to either school. Elsa, Merida, Anna, and Rapunzel go to the Disney School for Girls. Jack, Flynn, Kristoff and Hiccup go to Disney School for Boys.
But soon, they all meet and some sparks begin to fly.
Suddenly, bombs come and destroy most of the two schools, but everyone is alright, but all children are being shipped out of the country. Both groups of teens are sent away to the outskirts of London, where little Anna finds the magical world of Narnia and a whole new adventure begins for them all. (spoilers)
