Truly no greater feat of crime could ever hope to be pulled off after the Great Cookie Caper of 988 A.N. The culprits are still at large, but at this point, the concerned authorities have accepted their defeat at the hands of these wicked geniuses. The cookie jar, and all its precious contents, are gone, never to be seen by law-abiding eyes again.
I mean, okay, Celestia could have just asked for the jar and the kitchen staff wouldn’t really object, but man, that is just nowhere near as exciting. Besides, Celestia is a teacher, no? And that means passing on the skills she mastered onto her pupil. The next lesson is brushing the crumbs off you and, if possible, blaming Luna. No honor among thieves, after all.
That poor baker could have sworn the princess was in here. She’s late for her daily cake delivery.
