In the midst of some home “renovations”, Maxwell discovers a lantern. Thinking he has hit the jackpot of his dreams he quickly rubs it to release his dream-come-true: a wish-granting genie! Unfortunately for the Plunketts, this magic lantern is the home of a Meanie, an evil reverse-genie who gives the orders instead of receiving them. This Meanie has all the Plunketts become his slaves. Luckily Brady has avoided his spell. Brady discovers that there is an even more sinister plot to the Meanie's actions. If the Meanie succeeds in getting the Plunketts house key, the Plunketts and the Meanie will have magically switched homes. The Plunketts will become prisoners of the Meanie's lantern, while the Meanie will become freed from his lantern and live free in the Plunkett's house. Brady must act fast to stop this from happening. He tricks the Meanie back into his lantern and corks him in for good. As soon as the Meanie is back where he belongs, everything returns to normal, including the Plunketts.
