The Rainbow Bunchie, also known as the Final boss of the Internet, is a llama-like creature that is multicoloured. In essence it is an animation of the Rainbow Bunchie with a light-hearted tune in the background. To 'defeat' him you must watch the video without laughing.
It's teh final boss of teh interwebz!

*Laughs uncontrollably*

The Rainbow Bunchie defeated me!
