Suso Sáiz

A criminal produces an uncontrollable laughter to the population and Mortadelo and Filemón will have to stop him.

Wafer factory-owner P. Tinto and his wife Olivia want a child of their own more than anything else in the world. Years of trying, however, have left them with nothing but a pair of extraterrestrial midgets living in the spare bedroom. When they decide to try adoption, a series of misroutings and chance encounters results in an escaped adult mental patient arriving at their door with adoption papers in hand. P. Tinto and Olivia accept this without question and welcome him in as their son. Can this family arrangement work?

A terrible industrial accident changes little Dinki's life forever. Now Dinki's fate may ride on the wings of her eccentric friend Birdboy, a misfit who hides in the forest lost in his fantasies.
