There are these kids that go to this amusement park and the owner is crazy and turns people into these creatures and they work for him. There is a barn in it where it looks small and then the kids go inside and it is HUGE on the inside and at the owner's front door, for a guard, is a set of giant eyes. It has some comedy in it along with suspense.
