- Series 4 (10)
A pleasant afternoon of play is interrupted by unhappy grumbling sounds coming from the treehouse. Baby Bop is tardy and BJ is tired of his Sissy always being late for play appointments! Baby Bop arrives, oblivious to the time issue. Everyone nicely explains that learning to tell time is important for a variety of reasons. Dr. TickTock, a clock merchant extraordinaire and fix-it man, happens on the scene. BJ and Dr. TickTock initiate efforts to create a clock for Baby Bop, while Barney and the kids tackle the issue of teaching her how to tell time. In the end, Baby Bop gets her very own wristwatch that plays a very special tune.
