Lesson of Loss

26 “Lost and Found” June 6, 2004

Victoria has lost a necklace she got as a present from her parents a few days earlier, and goads everyone into helping her find it. In search of the necklace, her and her friends discover the Lost and Found Emporium, a storage room for all things ever lost by anyone throughout time. However, they’re not allowed to look for the necklace because whatever lesson Victoria gained by losing the necklace would itself be lost if she were to find the necklace.
