PopCap harvesting a money crop with Plants vs. Zombies on iPhone

We had assumed that putting PopCap's devilishly addictive Plants vs. Zombies on a handheld device was a recipe for commercial success. However, we didn't anticipate it setting a new sales record for the App Store, moving over 300,000 downloads in just nine days. At $2.99 a pop, the game has already netted the casual developer over $1 million on the iPhone platform alone.

We're sincerely hoping this inspires PopCap to explore other match-ups between things in nature and humanoid aggressors. Trees vs. Ninjas? Migratory Geese vs. Robots? The Ocean vs. Witches? Mega Shark vs. Giant Octopus vs. Everyone Else on Earth?
