Twilight being excited about casting a spell that should be fairly complicated for unicorns, is actually quite simple. But when scared and accidentally sending too much power into the spell when showing it off to her friends, it alters the spell just enough to mind swap all of them. With all of them scrambling to figure out what to do, they go and seek guidance from Celestia, she finds no cure from memory or in her books. She asks the pony's to leave to a secret base that she has in the Everfree forest that she uses for research on strange spells and effects the spells have on ponies. While staying there, things go wrong and now the Mane 6 don't know where they are, so now they have to find their way home. Not knowing the dangers at all of the new mysterious land, they travel to find out where they are, and who ponynapped them.
