Mrs. Larson is the mother of Gustav Larson. She might be the worst parent in all of Berk, stating that she would be willing to give Fishlegs her 'first born, Gustav,' during Gem of a Different Color. Of course, she seems to only slightly regret her actions later on in the episode, when the Changewings attack. The only good thing that can be said about her is that she seems worried about her son's life.
