Sure, it's fun being a boxbot when you're with all your boxbot friends. You can hang out at Grendel's, trick newbies into thinking you can all be opened, pull in your arms and legs and pretend to be a prim-- but in the end, we all exist alone, and perhaps being a box is not the ultimate existence. You dare hope you might become a robot.
And so you take yourself to the Whimsy Kaboom Robot Sanatarium.
Once you get through security you can begin the painful process of robotifying yourself.
Please, Unit Bender, Will You Help Me Become a Robot?
