Spirou and Fantasio set out for Palumbien, where they want to release the Marsupilami. However, this is easier said than done, as an unpredictable military dictatorship has seized power in Palumbien some time ago. To their great surprise, the two friends discover that the despotic head of state is none other than an old acquaintance: Fantasio's nasty cousin Zantafio. Like all volumes in the new "Spirou and Fantasio" edition, "Mushrooms for the Dictator" is published with enhanced features: sensitive new coloring, better paper and print quality, editorial additional pages with background information about the album and rare illustrations.
