Mrs. Mason is a minifigure who appears in Lego Harry Potter: Years 1-4. She is the wife of Mr. Mason, who tried to get a big drill from Vernon Dursley without success. While having a dinner party at the Dursley's, Dobby the house elf dropped a cake on her head. Naturally, Harry was blamed, and Vernon nailed him into his room. He was rescued by Ron Weasley and was taken to The Burrow.
