Lou is a red hoodie-covered creature with eyes of baseballs and buttons grinning mischievously from inside a school’s Lost & Found bin. Reminiscent of Sid from the Toy Story series, J.J. is a bully who takes his classmates’ stuff and destroying their beloved toys. Lou decides to teach this bully a lesson with some carefully crafted hijinks. 
The film ends with a dedication “For Dad”; as Dave Mullins' father passed away during the production of the short. Lou’s box also contains a football and a skateboard, which symbolize Mullins’ father and himself, respectively. Mullins was a self-described skater punk growing up, and his father was a big football fan. “The football ended up becoming a device for J.J. to annoy the kids at the beginning of the film and then connect to the kids later,” Mullins said of the story device.
