Caillou is traveling in style with his very first airplane flight and he's curious about everything around him: he loves looking out the window at the ground below and also, playing with the music system. Plus, breakfast on a plane is an adventure in itself! On another adventure, Caillou and his family leave for a day at the beach. There's so much to see and do! Caillou goes in the water with Dad and later, a seagull tries to steal his sandwich! Then Caillou sees a hermit crab and finally he and Dad build a sandcastle. Caillou misses his friend Sarah when she goes away on an all-summer trip to China. Grandpa tells Caillou about the time when his Daddy was a little boy and they went on a camping trip. Caillou loves the idea of camping and he and Grandpa set up the tent in the garden.
