Hmm, a rainy day find at Goodwill...a crusty old Furby with one broken ear for only $1.99!!!
..what to do, what to do?
Well ToysRUs happens to have the "Megaphone Voice Changer" on sale for only $4.50.
How about a little circuit bending and let's see if we can create a Zombie Furby!  

Caution, some people feel Furbies (the Hasbro toy first seen in 1998) are creepy right from the start.
While working on this project you should probably post warning signs outside your workshop....no need to freak out a curious passer-by ;-)

This Instructable will:
  1. give you a look at the insides of the classic Furby
  2. walk you through the steps of skinning the poor guy
  3. provide some details about his sensor system
  4. reveal rare video of the evil Zombie Furby including his new spooky voice.

Step 1: Why do you think he removes their skins, Agent Starling?

Picture of Why do you think he removes their skins, Agent Starling?
Skinning Furby
Skinning only makes sense here...this Furby was "well loved" shall we say...and besides, he'll look scary with just his innards showing. Besides we need to get at all those sensors.

To remove the fur in one piece, start by turning Furby over.
On the bottom back edge, use a sharp knife to reveal a zip tie that's holding the fur in place. Snip that zip.
Carefully peel back the fur, note that the ears are sewn in place at the very top, just another snip on each an you're almost there.
The top of the head has a bit of glue that's easy to scrape away and that's it.

An Ectoskelton? - now you're left with a plastic shell covering the Furby innards. Easy enough, just a few tiny screws on each side and you can pull it off the top.  As you do, carefully pop the microphone out of it's holding place (it's held in simply by friction)

Sensors anyone?
The Furby interacts with the world by the following sensors:
  1. Light Sensor in the forehead - Furby likes to sleep alot, but light will wake him up. 
  2. IR Sensor and Transmitter in the forehead - with multiple Furbies in the room they can talk to each other (Egad the horrors!)
  3. Tongue Sensor - Furby gets hungry alot, I found if I press his tongue with a screwdriver he says "Yummy" (I prefer a bit more Vodka in my screwdrivers)   
  4. Belly Sensor - a switch over the speaker activates when you pet or tickle his belly
    - do Zombies giggle? Furbies do!
  5. Sound Sensor - we already mentioned the little microphone that's on Furby's right side. Furby complains about loud noises.
  6. Tipover Sensor (not a Mercury switch see comments) - of some type, as Furby can tell when he's been turned upside down

Your main image set me on the wrong foot. I had no idea that your zombie Furby got skinned...
Neat idea to turn a Furby into a zombie! Besides hacking his voice some disfiguring might make him even more Zombie... Popped-out eye? One wheel instead of a flipper? Electronic guts hanging out somewhere...?

Just my sneaky way of getting people to check out my project without giving away the final project lol! Maybe I should have made the first image a dyptech
But yeah that sounds like fun for follow on hacks...I was just really focusing on getting the weird sounds

Nice Furby anatomy documentation! Note however, that Furbies use a much more eco friendly steel ball switch tilt sensor (like this: http://beelee-switch.com/uploads/130104/SW460-f.jpg.jpg), not a Mercury switch. That's the rattling sound you hear when you shake them (the steel ball rattling around in its housing).

Thanks for the "tip" :-)
This is totally awesome AND horrifying! Great work.

Thanks! Yeah maybe we need a caution icon we can put on Instructables that could give people insomnia ;-)
