Caillou is feeling frustrated while trying to build a model truck. He decides he wants to quit! Daddy suggests Caillou take a break and join him on an errand. Together, they stop by Erics dig site, where Caillou learns a little bit about archaeology and he learns that some things take time and effort, but the effort is worth it in the end. Caillou returns home to finish his model, and is proud that he did.
