At the back of a dusty old clock shop is a wall full of clocks. Big clocks, little clocks, silly clocks and sensible clocks. All of them ticking away to themselves, keeping perfect time. And right in the middle is one very special clock. This is the Tickety Toc Clock. As every hour passes, the clock springs into life to chime in the time. It all happens as regular as clockwork! But chiming the time isn't as easy as it seems! For behind the face of the Tickety Toc Clock lies an extraordinary wooden world where things definitely don't always run so smoothly... join Tommy and Tallulah Tockerty and their remarkable friends as they pull together to keep the clock ticking.
