I was playing the Pet Dungon level "Snowhope" where you have to torture-convert 20 enemies, and I discovered that I can set the Toybox pen to 10, and simply grab and drop an enemy out of the Toybox onto a tourture impliment without them having to be defeated in battle beforehand and taken to the prison.

Is that a bug or way as intended?
