Well, I bent this furby since I found it at the flea market for $1. I hadn't bent a furby and always felt like that's "one of things things you're supposed to bend" (like speak and spells and SK-1's). It's got an on off switch, an output, and a 9pin output for an atari joystick.
On the joystick: Up triggers the mouth button, the button is the "freeze" button, left is freeze+glitch, and right and bottom are both glitches, and the switch I added to the joystick just makes the motors on the furby go nuts. Not actually sure why.
That and it's eye(s) light up. Sometimes only one. again, not sure why.... but I felt it was lacking so...here's how he looks after awhile of painting, injuring, cutting up and burning:
I also decided he didn't need eyelids
Here's a video (before he was attacked).
EDIT: Here's the video
