The World of Craft City

Bitz & Bob is a children's animated television series that first found its home on CBeebies, the BBC's channel for young audiences. At its heart, the show follows two siblings—an inventive older sister named Bitz and her younger brother Bob—as they navigate the wonders of Craft City, a technologically advanced metropolis where creativity and engineering go hand in hand. Rather than presenting STEAM subjects (Science, Technology, Engineering, Arts, and Mathematics) as dry lessons, the series weaves them into imaginative play and hands-on problem-solving. Bitz, characterized as resourceful and quick-thinking, takes the lead in building, fixing, and devising solutions, while Bob chips in with his own energy and enthusiasm. Together, the pair tackle everyday challenges in their vibrant city, turning each obstacle into an opportunity to explore how things work. The result is a show that treats its young audience as capable thinkers, inviting them to see the world through a lens of curiosity, tinkering, and collaborative discovery.

A Colorful Ensemble of Friends and Toys

Beyond the central sibling duo, the show's world is populated by a cast of endearing characters, each bringing a distinct personality to every adventure. Bitz, voiced by Dolly Heavey, is the problem-solving, building, and fixing older sister whose rallying cry is 'Time for a Bitz brain blitz!' Her younger brother Bob, voiced by Duke Davis, wears a homemade cardboard robot-dinosaur costume and cheers on every triumph with 'Bitz blitzed it!' or an enthusiastic 'Awesome!' Purl, voiced by Maria Darling, is a soft rag doll and Bitz's closest friend. A perfectionist who adorns every project with glitter, she can be spotted on roller skates in certain episodes, exclaiming 'Oh my shiny sequins!' Bevel, voiced by Rob Delaney, is a monster-shaped action figure doubling as a power tool. Bob's favourite toy, he projects an 'ultimate action guy' persona with a surprisingly sensitive undercurrent, speaks in an American accent, and punctuates nearly every line with 'BOO-YAH!' Rounding out the group are Zip and Pop, a slapstick-loving brother-and-sister pair of zip-up cloth dolls voiced by Marc Silk and Maria Darling. Clumsy, curious, and impulsive, they find nearly everything hilarious, carry tools and mechanical parts, and detest sitting still, being alone, or being unzipped.

From BBC Studios to a Global Audience

The production history of Bitz & Bob reflects a collaborative effort between major media players. Originally, the series was a joint venture between the BBC and FremantleMedia, with animation handled by Jellyfish Pictures. When Boat Rocker Media acquired FremantleMedia's Kids and Family Division, the production responsibilities shifted under their banner, ensuring the show's continuity. The broadcast footprint is remarkably wide. Beyond its UK home on CBeebies, the series reached children across Canada (TVOKids and Knowledge Kids), South Korea (EBS), Sweden (SVT), Norway (NRK), Finland (YLE), Israel (Hop! Channel), Germany (KiKa), Latin America and Brazil (Nat Geo Kids), Hungary (Kiwi TV), the Czech Republic (Minimax and ČT :D), Poland (TVP ABC), Bulgaria (BNT 2), France (France 5), and Taiwan (GOOD TV). In select territories, licensing deals placed it on Nick Jr. or Disney Junior. In Scotland, BBC Alba aired a Scottish Gaelic adaptation titled Bitz agus Bob, echoing a similar localized effort from a predecessor series back in 2001.

Learning Beyond the Screen

A defining feature of the Bitz & Bob franchise is its commitment to extending the educational experience past the television screen. The show's core philosophy is that STEAM concepts—spanning science, technology, engineering, arts, and mathematics—come alive most effectively through imaginative play and active problem-solving rather than passive viewing. To reinforce this hands-on approach, the franchise includes a complementary short-form live-action companion titled Bitz & Bob: You Can Do It Too! This spin-off invites young viewers to step into the role of maker, guiding them through a related STEAM project they can attempt at home. By pairing the animated adventures with a practical, do-it-yourself component, the series creates a full-circle learning loop: children first witness Bitz and Bob brainstorming, building, and troubleshooting in Craft City, then replicate the experience in their own kitchens, gardens, or bedrooms. The result is an educational model that treats the viewer not as a spectator but as an active participant in the creative process.
