The Superninja balloon was the main character in Joel’s 2010 no-budget concept film Balloonmen (more about that one here). A lot of balloonoid heads exploded throughout Balloonmen. In preparation of a possible CG reboot for the film’s 10th anniversary, Superninja is featured in the first of a series of parallax animations entitled Kammerspielgifs.
The scene is based on an early recording for Balloonmen, an ancient vimeo link of which is embedded below.
Clearly the Superninja is a deeply troubled individual.
