As time goes by, various stange plants begin to grow on the island, eventually smothering the buildings and choking out the native plants. This strange red flora is refered to here collectivley as "Red Weed" in homage to its inspiration, War Of The Worlds, but the mutant plant life comes in many varieties - weeds, vines, ferns and mushrooms, among others.

The weed will not begin to grow untill sufficient rain has fallen - therefore, it could begin to grow within a day or so in a rainy game, or not until several weeks have passed in a dry one. Once the weed has grown to a certain size, it will begin to produce strange fruits.
