When the members of the Mobile Unit get zapped into sandwiches by the villain, Shelly Catessan, The Big O comes to the rescue. As she combs through video footage taken by Omar to celebrate their 100th case, The Big O must use clues she sees in the videos to figure out the order in which the agents were zapped so she can return them to their agent form. In the next segment, the Mobile Unit faces a series of challenges that Orla knew was coming from overhearing a sorcerer’s conversation 450 years ago. Through flashbacks, Orla shows the rest of the team the times she prepared each of them—unbeknownst to them—for the upcoming challenges. Part of the "Odd Squad" series.
