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. Numbers 3 and 4 are in the gym using the buddy blocks as a staircase to jump up and down. The Agents call in to report a problem at the beach and 5 takes on the mission. People are having trouble with their hands and feet getting mixed up - a boy playing football with his hands, a woman wearing shoes on her hands. What's going on?
