Sam and Amber have a great time with laser label guns which Uncle Zak wants them to use to sort shapes in the warehouse. He wants the 2D shapes separated from the 3D shapes. The children pretend they know the difference but they call up Numberella for reassurance. Numberella reminds them of some familiar 2D shapes then introduces them to some 3D shapes. Once Sam and Amber understand the difference between 2D and 3D shapes, they have a great time.
