Nightmare Fuel: Howard the Duck
As Dr. Jennings flees with Howard's girl, he begins to run out of energy. The way he recharges sent an entire room of birthday children running screaming, and a pair of parents regretting they had rented the show. Witness it here.
The possessed Dr. Jennings, and the horrid aliens, creep out any kid. ANYONE.
The scene where the bikers nearly chop Howard's head off.
