After the Hebrews left Egypt, the Egyptians found themselves in need of slaves. They turned to Japan, a country rich in people and ripe for the picking. As with any conquered people, the Egyptians procreated with the Japanese, and the Japanese taught their children Ninja skills. These offspring were the Ningyptians, an elite fighting race with +5 Stealth and +20 kick your ass.
Ningyptians can be resurrected by playing this crazy song my step-mother has on tape. This is also the best way to get killed by a Ningyptian.
Anna: What was that noise?
Andrew: I think there's a Ningyptian on the roof of the car!
