We call them by the proper name of les Schtroumpfs or de Smurfen but you will call them the Smurfs! The Belgian cartoonist Peyo, he created the Smurfs in 1958 based on the woodland creatures what live in the forests of Belgium. You see, the Smurfs, and to the lesser extent the Snorks (also created by a Belgian), show that our Belgian wildlife, even she is superior to yours!
Now they are making the film of the Smurfs (you English, read here) using the computer-generated imagery! Being that I am a privileged Belgische burger, I have already seen the, how you say, renderings. They look as real as the Smurfs I have seen in the forests of Wallonie (which, as you know, exists -- and is not in the computer, as M. Zapato says!)
When the Smurfs appear in the cinema, you and your children will learn that the Smurf-speak is double-plus smurf. Your English, she is pointless! Substitute the inferior English words with simple "smurf". Simple language for your simple English lives. When you are ready to think grand thoughts like we Belgians, you learn the Vlaams or the Français, or maybe even the Deutsch -- your choice! If you want, you come to Belgium and we teach you, yes?
