Joe and his pet dinosaur, Betsy, are ready for a fun-filled day in the snow. But as soon as they go out . . . Kerplunk! Crash! Bang! Betsy slides down the hill and crashes right through the ice, her big feet samsh the steps of the lions' den, and her sneeze blows the chimney off the bears' house. Poor Betsy! She's too big for her own good -- or is she? Lillian Hoban tells a warm and funny story that's just right for beginning readers.
