Ok so this is what your winning! 4 palladium TMNT Books, 

Mutants Down Under
TMNT Adventures
Road Hogs
After The Bomb

The rules are simple. 

1. Create a monster, creature, boss, enemy or something the player character has to come up against.  

2. It must be original, as in it cant be copied from some monster manual from some other game. 

3. Make it useable for any system, basically system agnostic. 

4. Give me your Essence!!!  (Just kidding this is not really a rule.)

The contest ends December 2nd. I will put all the names of the contestants into a random spinning, wheel of fortune style, wheel and the winner will be chosen at random.  You can create as many entries as you want but you will still only have your name on the spin wheel once.
