Horrible Highway (Pvz: HR)

Lawn
Its on a giant delivery truck. The last line of defense is a spare tire that rolls at zombies! Your protecting the other cars including Bloop's car.

Toxic Gas
Sometimes Smoke clouds come onto the lawn due to all the cars being around. Which when they are on plants they cause them become slower and weaker.

Red Light, Green Light
There's a traffic light on the right side. Every time it becomes red a lane stops moving, both plants and zombies can't move in that lane until it becomes either yellow or red.
