Steamroller Zombie

The Steamroller Zombie is the second new zombie encountered in Victorian London. The zombie drives a strong and slow steamroller that will crush any plants it touches. The Steamroller has three exhaust pipes that can be blown up one at a time by the Potato Sprout. If all three exhaust pipes are blown up, the Steamroller is destroyed.

Suburban Almanac Entry
Steamroller Zombie has his wits about him, that’s for sure. Through his strong mixture of intelligence and enterprise, he can steamroller his way through any opposition to achieve his goals, especially when that opposition is a lawn full of uncivilised plants and his goal is a divine brain soup.

Strategies
The Steamroller is a large threat to any plants close to the right of the lawn, including Fog-shrooms which can be crushed despite being invisible in the fog. Potato Sprouts are recommended to destroy the Steamroller, but a powerful defence can work equally well.
