The henchman drops a rope only on Velma, Shaggy and Scooby, but a moment later, Fred and Daphne are caught in the same rope, too.
The rope around the gang remains taut even after the ranch foreman has dropped the rope end.
When Shaggy and Scooby turned around to see the giant eagle, Scooby's nose turned brown for a split-second.
When the gang get caught in the rope by the foreman, Daphne's mouth briefly disappears.
Velma said she heard Daphne scream, but she actually gasped.
