Also known as a nodder, Hannah, wobbler or bobble head, is a type of collectible doll. During the seventeenth century, figurines of Buddha and other religious figures called "temple nodders" were produced in Asia. During the nineteenth century, bisque porcelain bobbleheads were being made in limited quantities for the US market. Many of the bobbleheads in the US were produced in Germany, with an increase in imports during the 1920s and 30s. By the 1950s, bobbleheads had a substantial surge in popularity, with items made of either plastic or bisque porcelain.

Typically, the bobblehead is popular and distinguished from other types of dolls by its big head, which is twice as big as any other typical doll. Instead of having connected strongly with the body, the head is connected to a hook or spring which keeps it moving even if there is a soft whistle blown. To make it more movable, the spring is connected in such a manner that also if anybody claps their hands or call someone's name loudly, the head bobbles. A bobblehead generally is 7 inches tall. However, a customizable bobblehead can be up to 9 inches tall as per the requirements of the customer. In the beginning, the doll used to be made with ceramics. But these days, the dolls are mostly made up of industrial latex materials. The ceramic one is delicate but attractive, or you can say sophisticated, whereas the artificial latex ones are mainly popular for their high durability.
