Suddenly it occurs to you that this isn't a real dog at all, but a clever fake! 'Why would they build a robot that looked like a dog,' you wonder, 'and why here, in this seemingly innocent house?' You pull your laser pistol from its holster and take careful aim at where you think the creature's central nervous cluster must be located. You pause for a moment, unsure of yourself but in your nervousness you accidentally pull the trigger anyway.
Blam! The noise of the laser and the recoil as it fires still baffle you, but when you look down at the mess on the floor you realize that you've made a terrible mistake! You bend down and listen, the sound of machinery wasn't coming from the dog at all, but from somewhere else, from somewhere deep beneath the house!
