Caillou is drumming and singing badly. Mom tells Caillou to quiet down so Rosie can take a nap, but he doesn't want to at first. Eventually he stops and heads off to the kitchen to get some cookies. They're hard to reach though, so he tries to use a stool and ends up spilling the cookies as well as a jar of honey. He tries to make honey cookies, but ends up making a mess. Mom comes in and decides that rather than get upset about it, she'll just have Caillou help her clean up. He does and then he and Mom make cookies together.
