I changed the batteries in my furby (2012) and it Still won't turn on!
My niece has a furby that's batteries died. We replaced the batteries but it still won't budge.
Try making sure the batteries are placed properly (+ -) (- +) or try to use a different brand of batteries. Possibly toying around with the ports could help as well.
make sure the batteries are in the right way lol
Make sure you use two different pairs of batteries just to see if the pair that you're using isn't broken too. ^-^. Hope it works out!
