The Steam Roller

Brown, Margaret Wise
 
Once there was a little girl. It was Christmas and her mother and father gave her a steam roller. . . .
 
A girl who’s given nothing for Christmas except a giant steam roller. She gamely sets out to drive it despite not knowing how, and squashes everyone in her way—including her mean old aunt, her teacher, and a policeman. Dismayed to see everyone as flat as a shadow, she informs her parents, who immediately present her with a giant steam shovel to scoop everyone up with. Soon everyone has been scooped back to normal, and a wonderful Christmas is had by all!
