Long story on the bass. She used to constantly play with it when she was young. Well I put batteries in it and it still worked. Well she was over helping mom make some food and it just kept going on and off, freaked her out. She is also terrified by mice. I found one on flea bay So what better gift than that with a mouse in its mouth that I set up to randomly turn on and off! I should have thrown a battery pack inside so when she took out the batteries it would still go on! Pretty funny when she noticed it. Still in her car and it has gone off a few times when she was driving!:rofl:
