Hi Olivia, I am the one that wrote the fixit link. I am more keen on the older furby,s . At some point the manufacturer changed them on the inside . I have 1 thats newer then a 98 . Not sure how much newer but newer. I had gotten it so mine would have a friend to talk to. Plus I wanted to see how they learn from each other. Not sure if thats true , had just heard it from someone. I had bought mine used at a yard sale . The person had no batteries said it worked . I figured even if it didn't , I had fixed mine I could this one. I wasn't so lucky. There alot different on the inside. First thing I did was new good batteries like Durrcel or ones like them. Cheaper batteries don't seem to do well in furby,s. No luck, so them I tried some light weight grease. Something like the kind they use in a sewing machine. But unlike the older furby,s were you can sometimes gently wiggle the gears free the newer ones you cant. Or I should say I could not. Did not want to try to hard & break a tooth on a gear since they are...

For battery corrosion : Depending on how bad the corrosion is . Take about 1/2 teaspoon of baking soda . Plus a drop or two of water & make a paste. Don't make it too thick or to thin. But thinner is easier to put on then thick. Take a Q-tip & rub it all over the inside of furby,s battery compartment. Rub it all over real good . Now let it dry. Now take a old tooth brush and brush the baking soda out. A little bit of residue left won't hurt . Just make sure that the little metal battery,s are residue free .Battery needs to have a good cotact. Now that should do the trick. Unless it went on to long then you might have to do Furby surgery to make sure that everyting is still all conected on the inside where the battery wires come out of the battery box. But try this first if it doesn't work get back with.

I have 2 furby,s & all I can tell you is if you have put new battery,s in . And fallowed the insturctions to reset ( they must be all new battery,s (4 new). I say this because a furby for some reason take a bit of juice to start up. And one bad battery will drain the other 3. If new battery,s and resetting has not worked you must operate on the furby .There are a few sites that explain how . They are all very simple to do. I was nervous to do mine due to the fact It was the first time I had ever handled mine. He had been in his packaging since 1998 .I had got another at a yard sale and wanted to see two interact. I took my time and it took a total of 30-45 min taking my time from start to finish. So just take your time and be gentle the operation will be a success.
