Three Hit Wonder

Three Hit Wonder is the eighth level of I, Zombie in Plants vs. Zombies, Plants vs. Zombies: Journey to the West and Plants vs. Zombies: Great Wall Edition. It is the first one to include the Imp and the Conehead Zombie and to exclude the Zombie.

Strategies
Use Bungee Zombies to steal the Magnet-shrooms. Use Ladder Zombies to place ladders on the Wall-nuts and Ladder and Digger combos if a Magnet-shroom is behind one. Use Imps to get rid of Squash or Potato Mines. Use Conehead Zombies and Buckethead Zombies for everything else.

The positions of the plants may be tricky at times, so there is no definite strategy. However, if you have a lane of Sunflowers (with Wall-nuts or Magnet-shrooms) and no Peashooters, Squashes, or Potato Mines, that is the easiest lane; one Imp will be able to clear such a lane. Also use Imps to clear the instant kills if there is just one and then an easy lane. Remember that if a Digger Zombie is digging, it can be killed by a Potato Mine underground, thus wasting 125 sun. Keep in mind that eight Peashooters, eight Sunflowers, three Wall-nuts, two Potato Mines, two Squashes, and two Magnet-shrooms appear in this level.
