Coco spends her birthday at an amusement park expecting her mother Gwen to join, but Gwen is pulled away when Mr. Wilkins and Fred reveal concert tickets and plan to go that evening. Adults argue—Gwen is accused of breaking a promise, Fred insists he traveled to get the tickets—and Gwen reluctantly agrees to take Coco. Then Gwen and the adults decide to attend the concert first because "Harry said he'd pick up Coco." Harry doesn't arrive on time. The episode ends with Coco abandoned on the ride crying, 'Don't leave me!' as the pickup remains unresolved.
