In her second cutscene, Lulu is seen sitting on a bench in Crystal Park eating a large amount of food, preparing for her face-off. Ruffington appears and looks at her. Lulu asks if he is hungry, to which Ruffington responds by barking. He then sits on the bench with her, and Lulu says that he is a good boy. Lulu and Ruffington are later seen sleeping on the bench together.
In her third and final cutscene, Lulu and Ruffington are shown still asleep on the bench. Lulu wakes up, and, upon discovering what time it is, runs away, then runs back to thank Ruffington for cuddling with her. Ruffington then barks.
