Succeeded by "Trumpton."
Each episode begins with a shot of a musical box which rotates while playing a tune. It is accompanied by the following narration:
"Here is a box, a musical box, wound up and ready to play. But this box can hide a secret inside. Can you guess what is in it today?"The lid of the box then opens and the puppet character that is central to the particular episode emerges. After a brief introduction, the background appears and the story begins.
