Robby and his sister Karla beg their parents to take them to a big carnival. Inside a large penned-in area, they see a dejected-looking boy sitting on the grass.

He eats the ice cream, delicately at first, then ravenously, noisilyand as Robby and Karla stare in horror, he transforms into a raging, hairy beast.
