Mom and Rosie go to the store; Caillou stays at home with his Daddy, and has a lot of fun imitating him and helping him with the chores. When Sarah shows Caillou and Leo her new remote controlled robot, the boys get a great idea to be robots too! They have fun taking turns 'controlling' each other with their own remote control. Leo comes over to play at Caillou's house. They have fun pretending to be bears until Sarah shows up wearing a GY (white Karate outfit). Sarah introduces Caillou and Leo to Karate and demonstrates a few moves. Later, Caillou wants to play with his animal cards but they have disappeared. A search soon reveals that Rosie has been playing with them, scattering them around the house. Caillou's new mission: to find them! So Caillou and Rosie head out on a safari, working together to find the animal cards. When Caillou visits Clementine, he is impressed to see Billy practicing on a Tuba. Soon, Billy's marching band mates arrive to practice. Clementine and Caillou make their own pretend horns with cardboard tubes.
