Vegemites! Like giant cockroaches, but dirtier and nastier and lots, lots bigger -- somewhere between the size of the tank of PMS on the left in this picture
and the Alaska State Ferry in the center.

Vegemites! They creep out at night, consuming sewage treatment plants, spent nuclear fuel rods, banjos, and their natural prey, Marmites!

Vegemites! They only grow larger and filthier when caught in a nuclear explosion!

Vegemites! Perhaps the end HAS come....
