Z4
A subspecies that looks slightly different from other models, mostly identified by its sexual organs, which although are still inside the car, are on open display. It appears to be agressive but is actually harmless. If bitten it may leave a nasty rash. It is an evolution of the earlier Z3 from 1865 which was actually a mutation of the Z1 which was a rarer mutation of the 3 series after a French Nuclear test in the South Pacific. The Z1 is rarer and worth more to a collector as a wall trophy, the Z3 however is very common and undesirable, despite a brief period when it was in fashion shortly after it was first discovered under a rock in the Nevada Desert
