The Creepy Creations of Professor Shock is the 14th book in the Give Yourself Goosebumps series.
Synopsis[]
You and your best friends, Jason and Stacey (who are twin siblings), take a job cleaning the garage of an inventor. You and your friends are told to avoid a particular door in the garage but you enter it anyway. Once inside, the three of you find a robot and a pinball machine, with a choice to press the button for either one.
Story A[]
You switch on the robot, which comes to life and destroys the room. A box gets smashed and you think it looks like something important, so you pocket the remains hoping to fix them before Professor Shock notices. At this point, Professor Shock comes in and deactivates the robot. He is so angry that you run away from the house. Back at home, you reassemble the box, which turns out to be a remote control. You discover that it controls all the machines in the world. This storyline then follows you getting caught up in a war between machines and humanity.
Story B[]
You switch on the pinball machine. Nothing happens at first; but then you hear Professor Shock coming, and you hide behind the pinball machine, along with Stacey and Jason. At this point, you all get sucked into a large mirror that was stored behind the machine. You then end up in a strange world where everything works backwards; and have to find a way to escape.
