The Smurfs are creatures invented and painted by Belgian artist Pierre Cullifor. Smurfs live in a forest in medieval Europe. Smurfs have many problems to solve in their village and are happy to help everyone, including their enemies. Smurfs are very similar to each other. All Smurfs are blue in color. Their growth is about 20-30 cm (three apples tall) and their lifespan is more than a hundred years. For example, Pape Smurf is more than 546 years old. The Smurfs wear white clothes, white trousers and a white hat, only Papa Smurf wears red clothes. Although the Smurfs on the series are very similar, each one is somehow different from the others.
