There's a lot of excitement at the post office! Pio of the Pigeon Post has his hands (or rather, wings) full. There is so much mail waiting to be sent out- but please make sure you use the right stamps! The children help Pio calculate the right postage. They'll need a little luck and, above all, some good math skills to get the job done. The player who can correctly calculate postage for the most mail wins.
