Katy is a big bulldozer that plows in the summer when it's nice out, and plows snow in the winter. But when winter comes and there isn't much snow, all the other plows are put to use and Katy is kept in. Until one day, a great snowstorm hits and everyone in the town, including all the other snow plows, are stranded! Now, it's up to Katy and her 'chug, chug, chug' endurance to get the town moving again. Includes snowy stickers to decorate the story!
