Note: This story is based on the Smurfs character created by Peyo. Although it figures in the same media as the Smurfs, its canonicity in the official Smurf franchise remains debattable. Given the rarity of this story, which has to our knowledge, never been republished, it nevertheless remains, by the incredible amount of visual and text informations it delivers in the two pages it lasts, a very cool piece of pop culture. Thanks to the authors!
