However, despite Hitler's insistence that they shouldn't be told and Goebbels' efforts to mislead them, his Axis partners Benito Mussolini of Italy and General Suki Yaki of Japan unsolicitedly appear at the submarine dock and invite themselves to the trip.

They incidentally land on Norom, where they discover the High Chief's camp, and as Seaman Benson does some reconnaissance, he meets Kela, the young female assistant to an alcoholic magician, who tells him that her master was hired by Paj Mub for an exclusive performance in honor of Hitler's upcoming reception.

However, Benson does his best to ruin the meeting: first, by spiking the served soup with pepper (this results in Hitler and Suki Yaki finding it unpalatable, while Mussolini thinks it bland), then switching the guests' wine with kerosene.

After making it back to the submarine, Hitler demonstrates his gratitude to Benson by punching him off the vessel, but he is surreptitiously pulled out of the water by his crewmates, who keep themselves hidden from the Axis leaders as they enter the boat for the return journey.

Benson relents from employing force, but then locks Hitler's cabin door and falsely announces through the intercom that the submarine is sinking, sending the Axis leaders into hysterics for a while, before he cheerfully reveals the Americans' presence on the boat.
