Soon she arrives at a spot with some camping tables and a birdwatching tower. She climbs up to view the scenery, but once there, she suddenly feels her tummy gurgle. She tries her best to hold it, but in the end she has to give up and mess her diaper.

On the way back down she wonders if she should go back home. Then she remembers her packed lunch and after eating she feels a lot better. Surely she won't let one messy diaper ruin her day, there's still much to explore in the arboretum.
