The evil mastermind Dr. Totenkopf died twenty years ago. The mysterious deadly sidekick is a robot that's been carrying on his project until the end. Totenkopf's plan was to carry all animals (like Noah's Ark) in a rocket that would kill everyone on Earth and give humanity a new start; the two tubes that Polly had were "Adam and Eve" and without them, the project could not continue. Joe and Polly stop the rocket from killing everyone on Earth. Polly uses her last camera shot taking a picture of Joe and he says "You forgot to take off the lens cap."
