S6, E12: To make the topic of "transportation" more interesting, Mr. Owl asks his students to build go-carts. Franklin, Bear and Snail team up for the class project, but have difficulty scavenging enough wheels. After making a lot of design modifications, they submit a two-wheeled go-cart that surprises the entire class. / Inspired by Franklin's heroics while pretending to be the Green Knight, Snail, a trusty squire, expresses a desire to become a knight too. The two friends embark on a challenging quest so that Snail can prove his worthiness. Along the way, more knights join the quest and repeatedly interfere with Snail's chance to show how brave and daring he can be.
