While Charlie is upgrading the antiquated technology at OIW headquarters, Tabitha and Jack are sent on a mission to learn about aquatic and semi-aquatic species at risk. Jack heads to Rondeau Park where he sets up a night-time stakeout, survivorman style, for the nocturnal Fowler’s toad that inhabits beaches and marshes in the park. He bumps into a herpetologist who explains why the toads are at risk and invites Jack to check out a breeding program for Fowler’s Toads. Tabitha meanwhile meets with a Mohawk biologist who introduces her to the long and perilous journeys made by American eel in their fight for survival. He also shows her some of the ingenious ways in which people are helping eels.
