Furby boom not working right

So, two days ago I purchased my first Furby boom off marketplace. She seemed to be working fine, though she ran through her batteries in like 48 hours. Is that normal? now though, I noticed that she constantly thinks I’m shaking her, even if she’s just sitting on a surface, and her speaker started making a weird clicking sound this morning when I tried to reset her after putting a new batteries. I know there are people that can tear it down and do all this stuff with fixing the motor and everything and it’s pretty amazing, but I am definitely not one of those people. So, is there an easy fix for this? Or am I just going to have to accept the facts?
