Clifford and Emily Elizabeth's hometown is celebrating its 100th birthday with a fair . . . and of course, a big parade! Clifford gets in on the fun, and is always there to help out whenever anyone's in trouble! Clifford is too big and clumsy to join most of the games and races at his town's centennial celebration. But when the bridge collapses, Clifford provides the support the paraders need to cross the river.
