Animated numbers solve real world mathematical problems, with help from real children. In the Cosy Room, 3's buddy blocks become cylinders. Number 5 has to fly out when a boy is having trouble with his chalks, a gardener struggles with an out-of-control fence post and a delivery man with a rolled-up carpet. All sorts of problems with different types of cylinders like a hat box, a tube of sweets and a cake are finally resolved, and the Shape Japer is sorted out. Number 3 is glad her circle sticks helped solve the cylinder problem, and they chase her.
