Yuna is trying to attend Jessica's birthday party in another attempt at befriending her, but Jessica invites Yuna only to humiliate her and have her clean up before and after the party. Hämsterviel is inspired by this and outfits Wrapper with the ability to trap his enemies in indestructible gift boxes.

Yuna's class heads off to camp where she volunteers to help out with the haunted trail in order to spook Jessica. She gets some extra help from Delores, Stitch, Jumba, and Pleakley in doing so. However, Gantu's not too far behind with both Toons and Spooky in hopes of catching Stitch.
