Objects found in the library or appear by magic are put into the top of the story machine (transformed from a desktop computer); Jelly, Jackson and the story maker then recite "Imagine, imagine, imagine a story!" and the story machine makes a book containing a story based on the object. The story in the book is then "read out" (although this is replaced on screen by live action or an animation). The first story is usually a Playbook (live action with small children), and the remaining stories are animated (cartoons), stop-motion animation, or puppets). The characters in the stories are fairly consistent, including Sniff and Wag (two puppet dogs), Blue Cow (a cartoon cow, created by Blue-Zoo), and Kevin the Spaceman (puppet). There is always a Blue Cow story and a Playbook - the other story varies between each episode.
