Yes, Gargamel made her out of blue clay, Papa Smurf did the “beautification”.

Thanks it's been over 40 years since I could tolerate the Smurfs. I tried watching it once as an adult and it was brutal.

They're U-social parasitoids; one reproducing female, one fertile male, and a large number of sterile male workers. They infest human areas and manipulate them into protecting their nests. Gargamel tried to inhibit their spread by introducing a sterile female to this colony after an unknown event caused their breeding female to disappear. Likely the colony would have raided another colony for its female if they had located one, making Gargamel's intervention necessary to prevent them looking for a fertile replacement queen.
