9. A House in the Sky

Mommy and Caillou go to visit an old friend of Mom's and her four-year-old son Kevin. Caillou is surprised to find that Kevin lives in a house in the sky - in an apartment building! He's never been in one before and finds it to be quite an adventure. He likes riding the elevator, and how the view of the city below is just like looking down on the ants in his backyard.
