Robo Watch / Sins of the Teacher. Flushed-Aways: Rube and Reg get flushed down the toilet and into the sewer, where they must survive without Rube's now water-logged circuits. Reg decides that the two of them should split up, and while Rube is thriving, Reg is barely surviving. RoboWatch: Reg re-opens a deserted beach, hoping to cash in on the tourism. He hires Rube to be the lifeguard, and to protect the beachgoers from Jowls, the great white Catfish. Unfortunately, The sun, surf, and lack of sleep are too much for poor Rube, and it's up to Reg to save the beach, oh, and himself too!
