A bobblehead, also known by nicknames such as nodder, wobbler, or wacky wobbler, is a type of small collectible figurine. Its head is often oversized compared to its body. Instead of a solid connection, its head is connected to the body by a spring or hook in such a way that a light tap will cause the head to move around, or "bobble", hence the name.

A figurine or statuette, is a small, three-dimensional sculpture that represents a human, deity or animal, or, in practice, a pair or small group of them. Figurines have been made in many media, with clay, metal, wood, glass, and today plastic or resin the most significant. Ceramic figurines not made of porcelain are called terracottas in historical contexts.
