Three Hit Wonder

Three Hit Wonder is the eighth level of I, Zombie and is the first to include the Imp and Conehead Zombie.

Plants
There are 25 plants in this level.
 * Eight Peashooters
 * Eight Sunflowers
 * Three Wall-nuts
 * Two Potato Mines
 * Two Squashes
 * Two Magnet-shrooms

Zombies

 * Imp (50 sun)
 * Conehead Zombie (75 sun)
 * Buckethead Zombie (125 sun)Three_Hit_Wonder_PowerStar856190.png
 * Bungee Zombie (125 sun)
 * Digger Zombie (125 sun)
 * Ladder Zombie (150 sun)

Strategy
Use Bungee Zombies to steal the Magnet-shrooms. Use Ladder Zombies to ladder 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 the player has 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's just one and then an easy lane. Remember that if a Digger Zombie is digging it can be killed by a Potato Mine underground.

Trivia

 * "Three Hit Wonder" is a reference to the term "One-hit wonder" (the number three comes from the number of hits the Imp can take).
 * In this level, it is actually possible to use a Digger Zombie to trick the Magnet-shrooms into stealing its pickaxe, which will cause it to pop behind the Peashooters, and eat the Brain. However, the player can only do this if their layout is very lucky.
 * It is the first I, Zombie level that the player use Conehead Zombies and Imps.
 * Starting with this level, the Imp replaces regular zombies as the cheapest option available.
