Tanjore doll

A tanjore doll is a type of traditional Indian bobblehead or roly-poly toy made of terracotta material. Its centre of gravity and total weight is concentrated at its bottom-most central core all the time so as to present a dance-like continuous movement with slow-damping oscillations. Hence it comes back to its normal seating position automatically after being tilted/disturbed anyway. Round-bottomed toys are unique, but other standing types are available too. Traditionally these toys are handmade and their exteriors are painted to an intrinsic sense of humour. Nowadays, they are also being made in plastics.
