Petri Dish
Petri Dish (formerly known as Secret Project PD-09) is a strategy game for 2 to 5 players in which each player is a germ fighting for dominance of a Petri Dish.
Petri Dish is a pyramid game designed by Andrew Looney. It is currently unpublished. A boxed version of Petri Dish is planned.
Petri Dish uses 3 Treehouse sets, 3 custom-designed dice, and a special gameboard.
The rules for Petri Dish will hopefully be released in some format soon, but I cannot say when.
