Mrs. Sourberry is a human character who first appeared in the Smurfs television cartoon series episode "The Clockwork Smurf". She was an elderly maidservant of King Gerard's, mostly seen in charge of cooking. During the time that Imperia had Gerard incarcerated in the dungeon, Mrs. Sourberry along with the rest of the kingdom was led to believe that Gerard was stricken with an illness that had lasted three years. Later she saw Gerard after he had left the dungeon with Clockwork Smurf, but judging by his clothes, she neither recognized nor believed that he was the prince, and taking him for a beggar boy looking for food, shoved him out of the castle before the guards could see him. It was only after he had returned to his kingdom with the Smurfs' help to expose his aunt Imperia's evil plot
