Episode Description: While erasing doodles for extra credit, Max and Molly stumble across a secret message from Aunt M hidden in the margin. It leads them to Burlington Bunker, a Cold War-era underground city in Corsham, England, where mysterious Morse code transmissions are being sent—possibly by the POGs or their underground allies, the Moles. With the help of a Problem Solving spy, Ames Blond, Max and Molly use pattern recognition, proportional reasoning, and division tricks to uncover a pattern in the coded transmissions. But just when they think the mission is over, they learn the transmissions are being sent... to Oshkosh.
