The series also served as the basis of an adventure game, developed by Xilam themselves and published by Ubisoft for Microsoft Windows and Sega Dreamcast called Stupid Invaders in 2000 – which was dedicated to its co-creator, Jean-Yves Raimbaud.
Five extraterrestrials from the fictitious planet Zigma B, Candy H. Caramella, Etno Polino, Bud Budiovitch, Gorgious Klatoo and Stereo Monovici, go on a picnic together in space.
They realize that if any human finds out that they are aliens, they could be captured and experimented on by scientists, so they take shelter in the attic of a house that is up for rent.
Etno Polino Candy Hector Caramella Bud Budiovitch Gorgious Klatoo Stereo Monovici Almost every episode features a new visitor, à la a "villain of the week" formula, who will come to the presumed "vacant" home.
While the credits do not specify who, additional voices include[citation needed]: All episodes in this season were directed by Thomas Szabó and aired on Saturdays.
Etno specifically researches, reacts and demonstrates the irrationality of Zelza's practices, and transforms himself into a rival psychic named "Madame Zetno" with the SMTV to try and drive her out of business.
However, when they arrive there, they are greeted by an angry Madame Zelza, Colonel Kenny, Crash Test Dummy, Norman and his mother, Princess Zibouya, Collector, Mrs. Durante and Molux, meaning that all of Etno's previous spaceships actually worked.
Unfortunately for them, a man who has been lost at sea and his wooden girlfriend (a figurehead of a mermaid from a galleon which he named "Simone") find their house and automatically move into it.
The Big Bad Wolf from the folk story of Little Red Riding Hood moves into the aliens' house and tries to eat them.
A film adaptation for the show titled Stupid Invaders was planned, but was never released for reasons unknown – what only remained was a short video posted online.
It was a CGI-animated adaptation of the show, where the four aliens (Etno, Candy, Gorgious and Bud) have ended up accidentally crash landing into someone else's house.
