Caillou is in the living room playing loudly with his drum. His mother comes in and tells him to play quietly because Rosie needs to take a nap. Caillou decides to play with another toy, but Mommy comes back in and wants him to be even more quiet.
Caillou sees a book with cookies and decides he wants to make some. Caillou goes to the kitchen and gets dizzy looking at things high up on the shelf. Then the jar of honey falls down. Gilbert comes in. Caillou opens the jar of honey, and the honey falls on the floor and goes all over the place. Caillou decides to make honey cookies - round ones, skinny ones, flat ones, and fat ones.
Mommy comes in and is very angry at Caillou for making the mess and they clean it up. Later they make cookies, but Caillou's Mommy ends up making a mess. They finish making them.
The next morning, Caillou's family eats lunch outside they have cookies for dessert. Caillou goes to sandbox and throws sand into the air. Caillou's Daddy asks him what he's making, and he says he is making a big mess.
