The dumpster.

After a time, Peach heard the creak of a door before she was jostled some more and steadied out once again. The was raised then toppled over, breaking it and freeing the princess as the chef walked away. She looked around to she was in the dumpster behind the castle then climbed out and heard a door shut. Peach rushed up the three steps to the back door and pulled, but it didn't budge and inch.

Peach turned, back against the door, arms spread across the walls, heart racing, head frantically darting about. She had been locked out of her own castle naked, covered in bits of cake, frosting, and some dumpster gunk. She calmed down and walked over to the dumpster; she slid down the side and sat with her knees to her breasts. All she could do was sit and think of a new way to get back into the castle or find some other source of clothing.
