Pulverizer

The Pulverizer is a robotic Chomper, basically.

Stats
HP: 12

Damage: 2 instant kills

Special: Eats the first zombie that approaches it and eats it in 10 seconds. Zombies with more than 2 instant kills of HP (except the Giga versions of ones with less than or equal to 2 instant kills of HP) are bitten for 8 damage a bite until they drop below 2 instant kills of HP. If it is destroyed by zombies, it explodes, dealing 1 instant kill of damage to nearby zombies.

Cost: 950 sun

Recharge: Fast

Strategy
These can cause massive destruction when used properly. They work great for Survival: Hard levels, since even Gargantuars go down when faced with these.
