The story behind Plants vs. Zombies 2 is largely focused on Crazy Dave, the speech-garbled, sauce pan on the head neighbor from the first game. You see, Dave ate a really good taco. It was so delicious he wanted to eat it again. He used his time machine to travel back in time, but things didn't go quite as planned. Instead of moving back a few minutes or hours, Dave pulled everyone to ancient Egypt. Since tacos won't be invented for several centuries, looks like he's got some work to do if he wants that second lunch.
