The fire chief visits Caillou s day care. Everyone learns about fire safety, they have a fire drill, and Caillou and Leo get to sit in the fire truck and sound the siren. Now both boys have exciting dreams of growing up to be a firefighting team.
After seeing Leo's new bicycle, Caillou wants a new one too, but his father shows him that sprucing up his old bike by reusing items from the house can be just as fun.
