Agent Olympia is not happy when an agent with the same name shows up at headquarters. In order for Olympia to keep her name she must challenge the other Olympia in various trials. Both agents are great at their job, but the one thing that will help one person to come out on top is a knowledge of measuring temperature. So how can they measure the temperature of water without a thermometer? One Olympia knows! Ms. O tells Olympia and Otis a story about a famous villain duo named Total Zeroes. They were the least oddest villains for years because they only subtracted or added zero to every thing they zapped which left no change at all. Until, they began to multiply zeroes and soon the whole world was in jeopardy, but why? Why would multiplying a zero be so dangerous?
