Tin animal toys. All of our cute little animals perform some sort of action via wind-up (clockwork) mechanism, friction power, hand power etc but not one of them requires batteries. They are the perfect pets to have. They require no feeding or cleaning up after and, best of all, when you're finished playing with them, they just go back in the cupboard waiting for next playtime. They never complain or make noise. Treat yourself to the perfect pet that will amaze all your friends by the cute tricks they perform, simply from the turn of a key, or the flick of lever.
