Birdcaged

It appears The Hero has found himself captured. But where would the evil overlord put him? Seems a regular prison isn't around or just wouldn't do.

So the bad guy sticks The Hero in a birdcage. This is usually done both to legitimately keep him locked away and to taunt him. On some occasions, the animal may be kept in the cage with the hero. Note that it doesn't necessarily have to be a birdcage, but is the most common form of this trope.

This becomes even more common when a character is shrunk or otherwise much smaller than their captor(s).
