Mr. Bean: The Animated Series

Mr Bean is painting a picture of Teddy when he accidentally squirts some green paint onto his brown wallpaper. Oh no! Bean needs to redecorate his room fast, but ends up painting all the walls a garish lime green, instead of brown. He's so terrified of Mrs Wicket finding out that when he goes to bed, he has some very weird nightmares with a rather sickly ending.
