In order to engage teens, and get them drinking more milk, DDB Vancouver created an animated webseries called Snack Time, featuring a carton of milk, chocolate chip cookie, and various other snacks including a marshmallow. This episode, Airport gives you a sense of the quirky humor involved.
As branded entertainment it's fun. Not quite as edgy as say Aqua teen Hunger Force, but it's just right for milk. I lol'd when I saw the milk in the kitty container in the cargo hold of the plane.
