Before the Ultimate Showdown of Ultimate Destiny...
Before the Potter Puppet Pals...
On February 28, 2001, Neil Cicierega released Hyakugojyuuichi!!, the internet's first "animutation". Two years of animutations later, Neil and his associates created a rap on the subject of animutation, called "Hyakugojyuuichi 2003". And the year after that, on February 28, 2004, a new animutation big-shot, Andrew Kepple, released the rap as an animation, giving hommage to animutation itself.
However, it was too big for Newgrounds.com's upload limit at the time, but now, for your viewing pleasure, on the 6th anniversary of Neil's little Flash animation that started the crazy trend, we, the animutation community, proudly present to Newgrounds...
Hyakugojyuuichi Forever!!
