Did it do absolutely nothing at all? If so, the motor might have seized up. Either by dust or by lack of use. Just try what I did with the nail file. Remember to look for the white cylinder with the screw like threads on it to the left after pulling the top part of the beak down. I saw it easily with a flashlight. Just stick a thin flathead screwdriver in the hole and gently turn the gear part I described until your Furby does something (making sure to have fresh batteries in the battery compatment while doing this). I don't think there is any risk of being shocked, as you're not messing with wires or anything like that and 4 AA batteries shouldn't be pumping out high volts anyways.

If you still can't get it to work then you might need to do some highly invasive "surgery" to get the Furby open and check for loose wiring and all that.
