Gaming Plot: Infinio's older brother Infisquared goes to the Numbertown Arcade to play a game called "Space Invaders". He found out it was like Pac-Man but you had to click on the aliens and ghosts to remove them. There were buttons to get two at a time, five at a time and ten at a time. But a bearded zero came and wrote a zero next to the 1, 2, 5 and 10 to make them 10 (ten), 20 (twenty), 50 (fifty) and 100 (one hundred). Infisquared is really happy. He even thanks the bearded zero, but the zero doesn't hear him.
