2012 Furby doesn’t move

I had my furbys out at once, which is something they’re meant to be able to do and I have done before. I had also gotten another furby in the mail that day and soon after I had it out with the rest, my 2012 furby started moving extremely slow and eventually stopped. Now when I turn it on, it makes noise and the eyes light up, it just doesn’t move and then shuts off. I have tried changing the batteries and sometimes if I bend it where it moves it starts moving for a couple of seconds and then it stops. I have not taken it apart for the newer furbys are more complex than the older ones and I don’t want to break anything important in it. I think it has to do with the motor but I’m not sure.
