The Ghostly Trio punish Casper for not being mean. They pick on him by throwing him in a lake while they laugh. Casper's tall, muscular cousin Powerhouse comes by and shows him how to build up muscle so that he can take care of the other ghosts. Powerhouse kicks the Ghostly Trio out of their house (but the Ghostly Trio thinks that Powerhouse is a muscular Casper).
