Or you could use a reindeer motor.

another one for free"

How big is it?

that big

The motor and linkage deal would probably work if you just want it to open and close continuously, but a hefty servo hooked up to a Scary Terry Audio Servo Driver board should make him talk.

if i use scary terry servo driver what kind of servo would i need and where would i get it

ha that is so funny

I am by no means an expert on servos, but I usually buy from Servocity.com. You could probably use anything with a little more torque than the HiTech 425BB (the more torque the better for this project, so I'd look at at least two or three steps above it). That said, you may not need a whole lot of torque depending on the way you set up the mechanism. Like I said, though, I'm probably not the person to ask. I'll let some of our resident techies fill in my gaps.
