*A plain red button in a large, sci-fi testing chamber.
The creatures it releases tend to look like a mix of human and animal DNA, but it can really be anything.
Generally, most of the creatures are fairly humanoid, and most can talk to some degree, some better than others.
You work for the company that made this button and these creatures, and it's your job to press the button and do whatever you want to the creatures while everything is recorded, either by you or by an observer.*
