Every time Twilight sits down for breakfast lately, the world needs saving. All she wants is to eat her breakfast just once in peace. At Sugarcube Corners, Twilight orders a freshly baked, blueberry muffin from a certain gray mare with a talent for making muffins. When Celestia appears to send Twilight to save the world, she encounters a small hiccup in that plan.
You see, Twilight is eating muffins. The end of the world can wait.
