Princess Twilight is in her library and she finds a spell called Destinies For A Day. Twilight finds no harm in the spell...once she casted it of corse. It turns out that nothing happened, until she sees her friends. They have all become alicorns!!! Twilight is very confused as she flips through the book that she found the spell in. The next morning they are all back to normal, but to Twilight's surprise, they want to be alicorns again! (Yes even Rainbow Dash)
