So Clark Kent and Jimmy Olsen are assigned to try to find a 'missing link' in Africa. Of course, Kent heads out to search by himself as Superman and leaves Jimmy in charge
This panel makes me crazy with laughter. Look at the alligator just trying to munch on Superman and I love that the animals decided to team up, making them much smarter than 90% of the villains that try to takes Supes on their own.
But everything is great back at camp because Jimmy is asleep on the job. What could go wrong? Marauding Monkeys, of course!!
Well, as the story progresses, Jimmy ends up yelling himself hoarse and ends up being mistaken for the 'missing link'. Superman decides that he will teach Jimmy a lesson and using his powers frustrates every attempt of Jimmy's to try to communicate. Needless to say, the researchers that Clark and Jimmy have been staying with end up in the path of stampeding water buffalo. The researchers figure that the jungle boy can save them, they throw Jimmy in front of the buffalo. Superman slips away and...
... stops the stampede by coating their hooves with liquid rubber. Heh heh. I never figured that Clark Kent was a tree hugger.
