The Dancing Baby, also known as Baby Cha-Cha and the Oogachaka Baby, was never meant to be seen by the public. It was a stress test. In 1995 the company Unreal Pictures was building Character Studio, an animation plugin for Autodesk's 3D Studio Max, and needed sample files to impress developers. Animator Robert Lurye took a file of an adult skeleton dancing the cha-cha, added air guitar and shoulder shimmies, and the team forced that motion into a scanned plastic doll sold as Toddler with Diaper, model number 5653.

The result worked so well it was unsettling. Unreal Pictures co-founder Michael Girard found the realistic movement disturbing and shelved it, a textbook case of the uncanny valley. This episode follows the file's escape from the lab: rescued by a LucasArts animator, squeezed into a looping GIF that suited dial-up connections, remixed by fans, set to a Blue Swede song, and finally carried onto prime time television.

• Fitting adult bones to a toddler mesh required vertex weighting, with the Physique software calculating how the digital skin should stretch. The file was shown at the 1995 SIGGRAPH conference.
• When Character Studio launched in August 1996, the baby was left out of the highlight reel. Ron Lussier recombined the pieces, exported an AVI, posted it to a CompuServe forum, and emailed it to coworkers.
• Web developer John Woodell converted the heavy video into an animated GIF, which played inside browsers and email and looped forever.
• Rob Sheridan, later an art director for Nine Inch Nails, ran an unofficial fan page that collected variations like samurai baby and rasta baby. None displaced the original.
• Paired with Hooked on a Feeling, the animation reached commercials, news broadcasts, and the drama Ally McBeal between 1997 and 1998.
