Grandpa's got a surprise for Caillou on their trip to the park - it's a remote control sailboat! Caillou is eager to race against the other boats on the pond. He imagines himself as Captain of the fastest sailboat ever. In his eagerness to win however, Caillou goes a little too fast and the boat capsizes. Caillou is sorry he didn't win the race, but he still had lots of fun and is eager to try again next week.
