What's on the menu today, kids? SPATTERED REPTILE BRAINS. I like the way the caption goes out of its way to tell us Frank missed the first time, and this guy's probably dealing with a crushed layrnx.
It's a rather desultory outing. I think the audience was happiest when Frank was flying in an air-ship. Subs were cool, of course. But the thrill of an electrical cab wears off quickly. Unless there are monsters. Monsters with spatterable brains.
