Professor Bacterio has invented a new contraption called the "Telefrusky," which allows one to travel to the world of cinema. He decides that Mort & Phil should journey to "Jurassic Park" and bring back samples of dinosaur DNA to restore Ofelia to her natural size after she was reduced to a miniature form following an experiment with a weight-loss elixir that Bacterio had also concocted (naturally!). However, the agents are mistakenly transported to a Wild West town in America called Western City, complete with a sheriff, a saloon, a gallows, and even Native Americans. In this town, Billy the Kid and his gang will steal the Telefrusky's diamond, and the agents must recover it to return to our dimension.

A fantastic point & click adventure in which you can control Mortadelo or Filemón according to your preferences. Switch between characters and choose who will perform each action.
