In January, there's a lot of snow on the ground. One day when Henry and his big dog Mudge go outside to play, they see a sign in a store window. It says: SNOWMAN CONTEST, SATURDAY AT THE PARK. Henry runs home to tell his dad. On Saturday, the park is filled with people building all kinds of fancy snowmen. There are many dogs there, too. While Mudge makes friends, Henry and his dad get to work. They will need to make a very unusual snowman to win this contest!.
