Can my furby be saved?

i have a pink furby boom that was bought in 2013-2014 and it has been sleeping in the closet for at least 5 years. today, i decided to turn it on, but its acting really weird - when its waking up, it does a weird tic tic tic sound, and when it finishes yawning the tic stops. when you turn it on for the first time, it acts normally, it just doesnt move - but it still recognizes if you touch it or if you feed it, but it goes back to sleep like 30 seconds after. when you try to turn it on again, it doesnt react to anything, it just talks until it dies like 12 seconds later. ive tried changing the batteries, resetting it, shaking it a lot (lol) but it still doesnt turn back on :( is it really dead? can i still save it?
