Books with title Miss Osborne-the-Mop by Wilson Gage

Mixed-up magic! Jody and Dill took a dim view of having to spend a whole summer vacation with each other -- until the day they stumbled onto Jody's unexpected magical powers. Who wouldn't admire a girl who could turn you into a squirrel just by saying: "Oh, shut up and be a squirrel, will you?" Jody rushed headlong into the excitement of witchery. A magazine made a luscious orange-frosted cake; a stick, a shiny red motorcycle. But magic cannot always be controlled. When Jody brings a dust mop to life, it refuses to go back to the closet. Jody and Dill are faced with the problem of how to keep a mop busy, happy, and out of sight of any adults! "Young readers will relish this very funny story. . . . Here is fantasy that really comes off, well-written, fast-paced, believable." -- School Library Journal (starred review)
