I'm Your Fool (2020)

Amelia Grey's interested in Kay Jamerson, but he's living in his own world, not really thinking about girls. So, while they're stuck on a Saturday volunteering at their school's carnival themed showcase they ditch it and head off to an eel filled creek. The day ends in disaster as they get into a fight about feelings and other gross stuff and Kay loses his car keys leaving them stranded, unable to leave the creek and get out of their costumes.
