Numberjacks - Series 1 - Zero the Hero

Comedy adventure series, aimed at four- and five-year-olds, in which animated numbers solve mathematical problems in the real world, with input from real children. Number 3 is organising a game of hide-and-seek, but 0 hasn't turned up to play. Agents report that a boy is having trouble with a chef hat that is stuck on his head. All the numbers become particulated and disappear, leaving 0 to save the day with the Brain Gain machine - which retrieves all the numbers and sets everything right.
