Sleep Away Camper

From Ben10versepedia

Max and Gwen are sleep, and Max is snoring rather loudly, and Ben can't sleep because of that. Ben wakes up Gwen and she tells him to stuff his air with tissue to not hear it, but he still can't get to sleep. So he goes outside but it starts raining. He tries to go Grey Matter to crawl into a small, quiet place to go to sleep but instead goes Ripjaws so he falls asleep at the bottom of lake.
