1. Uncontrolled ferret infestation. If this is such a danger that the State of California had to ban ferrets, it should be playable in the mod. After all, the State of California doesn't bankrupt itself pursuing idiotic notions!
2. Robots. Girl Robots. 'Nuff Said.
3. Steam-powered Socialist Socialites! (Okay, maybe a bit too much like #2 above.)
4. Terrible Tungsten Tortoises!
5. Madonna, Lady Gaga, Britney Spears, and Joan Baez form a super-group and start touring Ponovosa. (Okay, far too much like #3 above.)
6. Attack Kelp.
8. Anthrax. Not the disease, the 80's metal group. (Okay, too much like #5 above.)
9. Ponovosa is converted to a giant golf complex and battles have to be booked three months in advance and attack parties can only foray out in foursomes.
10. Something else that MorrisB is keeping in his twisted mind. (I really hope it is nothing like #2,3,5 or 8 above.)
