Episode Description: To stop the POGs’ prediction network, Max and Molly realize they need help—and fast. However, they are torn on whether or not they can trust Charlene.  To test her honesty, they recreate an experiment with a “lost” wallet stuffed with cash.

Episode Description: During a break while playing Bingo – Max and Molly discover how probability shapes games of chance—right before a mysterious emoji message pulls them back into the hunt for the POGs. A hacked toy, a glitchy wi-fi signal from 1998, and a massive hidden server reveal the POGs’ terrifying “Prediction Calculator.” Now, the only way to stop them is to track their servers across time.

Episode Description: While warming up indoors on a snowy day, Max and Molly review their mysterious clues about the POGs—until Max’s Alexa begins acting strangely. Decoding a message leads them to the famous toy store, FAO Schwarz, in 1998, where they overhear a secret meeting of sinister toy avatars plotting chaos across time. To stop them, Max and Molly decide they must become… moles.

Episode Description: Summoned to a High Tribunal – Max and Molly must defend their claim that a Mole has infiltrated The Order of Problem Solvers. After passing a high-pressure test, they argue their case—but nothing goes as planned. But in a twist, they discover that nothing might actually be the answer to their problems – and that perhaps the best Mole… is no Mole at all!
