The next morning, the guys discuss what they've learned from the mama. They've heard that she's defending her calf, so they're determined to find out what's going on. They need a boat, a drone, and a battery-powered transmitter to get the job done. They also need to figure out a way to communicate with the mama, since the military is going to come in and kill all the fish they depend on to survive. The guys decide to play the baby's cries on the transmitter, which should attract the mama and keep her alive.
