If as Carol Channing and Marilyn Monroe sang that Diamonds Are a Girl's Best Friend than it would have been in Lorelei's interest to befriend Huntz Hall because in Jungle Gents a sinus operation has left Sach with a nose that can smell where diamonds are located. What to do with that but go to Africa and do a little prospecting.
The whole Bowery Boys gang including Bernard Gorcey who once again leaves Louie's Sweet Shop to accompany Leo Gorcey, Huntz Hall and the rest to the Dark Continent. Of course diamonds already mined and out of the ground are easier to find which leads the boys into contact with some smugglers played by Patrick O'Moore and Rudolph Anders.
Really at this point the series was sliding downhill. How many more plots can they have where Huntz Hall develops some strange power that gets them all in a jackpot?
