Animated numbers solve real world mathematical problems, with help from real children. 6 and his buddy sticks are measuring things in the Gym. Out on location, things are changing length, including pencils, trousers, and brushes. It's all the fault of the Shape Japer. The Numberjacks send Brain Gain to change things back to normal by matching them to things that haven't changed. Later 6 uses the buddy sticks to measure ties and mops and restore them to normality. They change the size of the Shape Japer and she goes off in a huff.
