In "Little Big Smurf," Papa Smurf is shown experimenting on a sunflower as to test a spell to return a giant Snappy to his normal size. However, sunflowers did not grow in Europe until they were imported from the Americas in the 16th century. The background of the Smurf cartoon series is the late Middle Ages (circa 14th-15th century), early for the appearance of sunflowers in Europe.
