ZITHIA started out as a Water Craft Research Center (WCRC) controlled by a penguin named Z just off the coast of the USA. In 1998, ZITHIA was accidentally untethered and send adrift for two years. In 1999, Z rebuilt the WCRC into a mechanical country. In 2001, 2004, and 2007 ZITHIA was updated to ZX2, ZX3, and ZX4.
