Comedy adventure series, aimed at four- and five-year-olds, in which animated numbers solve mathematical problems in the real world, with input from children. Numbers 4, 5 and 6 are in the gym practising jumping on the buddy blocks, who are lined up from 1 to 6 like a staircase. The Agents call in to report that there is a problem with things being forced off things: toys off a toy truck, a skateboarder off his skateboard, an entertainer off his unicycle, and a man off a bench while he's enjoying his lunch. What is more, Spooky Spoon is mixing things up. All the things that were on are now off, everything's being mixed up and suddenly things end up on top of things they shouldn't be. It takes a great deal of Brain Gain to get things put right, but they make Spooky Spoon cross and she messes up 4 so that he ends up on top of a tall pole. The Numberjacks remember the exercise they were doing in the gym and 4 manages to jump down using different steps. They send Spooky Spoon to the top of the pole and she disappears. Order is restored and 4 can return to base.
