Plants vs zombies eat brains. Is Dave crazy? He was taken away by bungee jumping. Why not eat?

This. . . Forced explanation is as follows:

Zombies invade the player's home, indicating that "zombies eat your brain" refers to the player; Although Dave was taken away at the last level, the zombies were preparing to invade the house, so they didn't eat Dave.

It's just a brain hole, but please adopt it.
