It's ridiculous. Smurfs in smurf village are A sexual. They don't have reproductive organs under there white pants.
Baby smurfs are delivered by the stork and Smurfette well she was sent as a spy by Gargamel. But Gargamel isn't that smart. He's been fooled cause he is unaware. ( It is what makes the show so funny right) Let me explain.
See all male and female Smurfs live in other villages, far away. Gargamel doesn't know about these smurfs. They reproduce normally, and they have two types of offspring : male and female . Of course which they keep but they also have asexual offspring, which they give to the storks. So all the smurfs on TV that you know that live in the smurf village are the A sexual ones that the Storks have delivered.
Pappa Smurf well he guides them but also has no dick.
Your a smart guy so suprised never picked this up as a kid? It isn't that complicated.
