Wally's over-protective mother goes shopping and leaves the boy in the care of Barclay, the chauffeur. Wally orders him to "drive down some alleys" and comes upon the gang, who are riding on a makeshift merry-go-round powered by their mule, Algebra. To make the mule go, all you have to do is sneeze. To get her to stop, you need to sound an alarm clock. The action is soon relocated to Wally's mansion, where the mule runs rampant every time somebody sneezes, which is often.
