Everyone knows that Francine is rather bossy and somewhat independent, but when she insults Muffy on her street hockey playing skills, it would seem she's gone to far. After a bit of crying, Muffy decides to make a bet with Francine --- she'll give Francine the Princess Peach watch that she's always adored if Francine can be nice for an entire week. Francine takes the bet seriously and pretty soon, her behavior is barely recognizable to her friends. Worried that she may be bottling her anger, Arthur and the rest of the group try to get Francine to let off some steam, before she ends up doing something really rash. (thetvdb.com)
