The "Dancing Baby" is an animated 3D model of a baby doing the Cha-Cha dance. A widely distributed version of it includes a clip of the song "Hooked on a Feeling" and has become known as the "Ugachaka Baby".
In 1996-97, the animation became one of the very first viral Internet memes, spreading quickly through email.
It was eventually featured as a recurring hallucination on the
television program Ally McBeal - whenever Ally saw the baby, it
represented her biological clock ticking.
