Griselda is the queen of Valhalla and the wife of the viking King Yorik. She appeared in episode 62, "Maid of the Myth".
She was angry when Mrs. Beakley arrived in her land but her husband gave her a gold necklace and lots of other stuff. The queen was jealous that her people were interested in Mrs. Beakley's singing voice but she had a plan for her. Griselda took a bag of powder and put it in a cup of water so Mrs. Beakley would lose her voice but Launchpad drank it by mistake and lost his voice. At the end of the episode, Yorik said he would teach his wife to be a good queen and teach her to share with the outsiders.
She has long, blonde hair, wears a jeweled crown, wristlets, and bracelets, necklace, and pink dress.
