I was thinking that plants and zombies that touch the boulder trap would activate a boulder that acts like lawn mower for both - plants and zombies - but then those lanes would be totally protected. Maybe there is plant boulder and zombie boulder that kills plants or zombies only respectively. But again, you could plant puff-shrooms on them and kill zombies. If zombies would kill themselves by stepping on those tiles instead, it'd be even easier :/

As for flame traps - zombies that step on would be killed by fire and same goes for plants but zombies wouldn't be able to go over it and reach your brains :/

Maybe those traps could appear and disappear like chinese power tiles. I think Boulders will only work once, aactivated by any plant or zombie and Flames will throw flames for a short period of time, maybe at a random interval or a preset one, making it a very chalenging element, since, periodically, you will loose all your defenses in front of it (if one of those flame tiles is placed in the 7th column for example, it would really help you out, but imagine one placed in the 4th or even 3rd column - it would rather help zombies, because they will come faster than you could gather enough sun to rebuild your defenses, after it is activated)

I also think that Snapdragon statue seen at the end of the map is a sign of those flame tiles, trowing flames in the line in front of it (I still cant see how they would figure his placement on the lawn)
