The only human character in the show is Mr Mopple (portrayed by Chris Jarvis), a groundsman. Whilst doing his jobs, Mr Mopple hears a noise from the house which tells him that there is a story to be narrated. The house magically appears to come to life with a superimposed puppet face appearing on the house. As he steps inside, the face on the outside wall says, "Step Inside, all those who love stories, look and listen, we've tales to tell of fun, excitement, magic, adventure, tears, fears and laughter. Surprises as well. Step Inside."

Inside the house are the non-human characters, which use a mix of animated faces and puppet hands:

• Twinkle, an animated cat
• Boris, an anthropomorphised bookcase
• Chloe, an anthropomorphic clock

Boris the bookcase provides a book and Mr Mopple sits down to narrate the story. The characters themselves often argue among themselves, along with Mr Mopple keeping the peace. Mr Mopple provides an array of voices for every character in the book while narrating. When Mr Mopple has finished narrating the story, he leaves the magic house (with the face on the outside wall closing its eyes and disappearing entirely) and goes back to work.
