Everything has settled down into a routine, with Ro-Man looking for the humans and them hiding out behind their forcefield. Johnny decides to go for a walk stumbles across the monster's cave, which is fairly conspicuous since the radio is constantly spewing bubbles. Immune to the effects of a cosmic ray which destroys rockets and space platforms courtesy of the Professor's miracle serum, our little commune is still doomed if Ro-Man finds them. Alice uses this excuse of impending doom to fall for Roy, lucky thing considering he's the only male alive not related to her. The honeymoon is short lived, as the gorilla starts finding people and strangling them, but he can't kill Alice.
Caves are perfect for social gatherings.
Lightning causes some really weird stuff to happen. Space gorillas love bubbles. Rather than calling attention to your location, a forcefield made of copper wires arcing electricity makes you invisible to scanners. Lumpy women should not wear tight, backless halter tops. Antibodies will protect you from cosmic rays.
