The Kraatu is a BIONICLE promotional set. Its instructions emerged on LEGO.com in 2004 but it was likely not released. Nearly nothing is known about it. The Kraatu had no storyline importance, but it was likely some sort of Rahi. BIONICLE story team member Greg Farshtey suggested that the Kraatu could possibly be a puppet that the Matoran of Metru Nui used for recreation.
