The IZ (stylized as iZ) is an electronic musical toy released in September 2005 from Zizzle. Taking the shape of an extraterrestrial tripod creature, the iZ allows users to interactively manipulate music by twisting particular parts of the figure's body as well as add sound effects to pre-recorded sound from a connected audio device. The toy also acts as a dancing speaker.Since the original release it has been available in five color schemes: green/orange, dark blue/light blue, red/yellow, purple/green, and chrome/orange.

iZ was developed by Roger Shiffman, who also created the Giga Pets, Furby and Poo-Chi toys. It was explicitly explained during the development phase that a "new Furby" was the aim. iZ is designed to seem like it has a life of its own and does things out of its user's control when there is interaction with it.

In 2006, McDonald’s had a promotion for the toy with Happy Meal. These made music or light in various colors, such as grey, yellow, pink and more.
