Lilo wins tickets to the Elizabethan Fair and invites Elena, Teresa, and Yuki to join her. However, Mertle refuses to go because she does not want to have Lilo around, and Stitch is not allowed inside because no dogs are admitted. They team up to catch a metal-eating experiment on a rampage. Eventually, Gantu is allowed to capture Tank in order to save Mertle and Stitch. The hula girls take Mertle back, and Lilo apologizes to Stitch for neglecting him.
- Moral: It's important to have new friends, as long as you don't neglect your old ones.
