A lemur robot called the LEM-R (an acronym for "life-emulating robot") is sent to the lemur habitat so it can learn from Julien before it heads to Mars, which makes Mort jealous. The penguins want to teach the robot skills it really needs for its mission to Mars so they kidnap it, but during training, it accidentally explodes, making Julien depressed and Mort happy. (Maurice tries to get Mort to cuddle Julien's feet) Filled with remorse, the penguins rebuild it and the robot is sent to Mars. However, upon arriving on Mars, the robot is eaten by a martian making Mort excited, while Skipper points out a lemur shouldn't have been sent to do a penguin's job. (subfactory.fr)
