Four children in Mrs. Clark's Kindergarten class don't want to go on to first grade. Emily doesn't even want to be at school, preferring to stay at home. Thomas and Maria love Kindergarten and want to stay there forever. Jason doesn't care about anything. He just wants to play all the time.What can Mrs. Clark do to help them? She has only one solution: call Dr. H.M.S. Clickity, the almost famous inventor of the well-known but seldom seen Clickity Clock.
