The tranquilizer gun that is used on the lone werewolf that escapes from the line at about 10:55 is actually a Nerf Maverick toy dart 6 barrel revolver blaster. The top rear of the blaster has black tape over where the Nerf logo is. The type of darts that this blaster fires are foam with a soft rubber tip, not a sharp tipped tranquilizer dart.
The word "werewolf" is never said in the film.
