My sister said four of their zhu zhu pets all wake up and start zooming around on the middle of the night!
Once there was one under her pillow and she didn't know till it woke her up at 2am lol!
DS was given a little john deere four wheeler for his birthday and it has buttons that say different things when you push them, an ignition sound, a song and blinkers!
It regularly zombifies and continuously says 'we're big and strong!' over and over and over and over again!
Scares the bejeebers out of me!!!
