Which British children's TV program is about two rag dolls who live aboard a narrowboat called the Ragdoll?

"Rosie and Jim" is a British children's television program produced by Ragdoll Productions. Rosie and Jim are two rag dolls who live aboard a narrowboat called the Ragdoll, which is from Birmingham. There, they sit with a concertina on their lap, and come alive when no one is looking to explore the world that they pass by on the canal. They learn to experience things by following the Ragdoll's owner on his or her adventures, and secretly joining in with them. Usually they end up causing trouble, but they are never detected because no one ever sees them.
