The Super Material Egg is the fifth egg in Egg, Inc.
Lore[]
Further research post-Rocket Fuel Egg discovered "Iron Chickens" that laid a "programmable metal." Applications included a size-changing knife, a car that could convert from SUV to sports, bullet-proof, fire-proof, self-repairing, comfortable clothes, and three-bedroom houses made from super material "kits" that started at a mere $30,000.
Appearance[]
These eggs appear to be completely made of a metallic material in what is presumably its base state.
