Bag of Kidnapping

Roquefort: Duchess! Kittens! Watch out for the ... (Edgar traps them in a bag) sack.

—The Aristocats

Penelope: Boy, am I sleepy.

Hooded Claw: Good, it's time you hit the sack (Evil Laugh) literally!

—The Perils of Penelope Pitstop

A tactic mostly seen in Western Animation: The villain usually sneaks up behind the target and throws a large burlap sack over her head and carries her off to his hideout; this usually happens to a Damsel in Distress or Snooping Little Kid. The target is almost always female, but it can happen to male characters, just not as often.

Examples of Bag of Kidnapping include:
