Professor Barbenfouillis and five of his colleagues from the Academy of Astronomy travel to the Moon aboard a rocket propelled by a giant cannon. Once on the lunar surface, the bold explorers face the many perils hidden in the caves of the mysterious planet.

Based on the Happy Hooligan comic strip, by Frederick Burr Opper. Happy speaks with someone in the park and takes a trip to the moon on a rocket that looks like the front half of a current racing car, where he is made king of the moon. A ballerina does a shimmy and Our Hero winds up back in the park being accosted by a cop. The inference is that he has fallen asleep and dreamed the entire trip.

In the international race to the moon, the Norwegian mission is led by brilliant inventor Reodor from the village of Pinchcliffe. With Luca the Magpie as the brave astronaut, what could possibly go wrong?
