In "Gargamel's Giant," Gargamel needs as one of his ingredients in making his giant are chokecherries. While Papa Smurf is correct that chokecherries do not grow in Europe (they are native to North America), they were unknown to Europeans until the 17th century. The background of the Smurf cartoon series is the late Middle Ages (circa 14th-15th century), early for the knowledge of chokecherries in Europe.
