Tankorn

Tankorn is a plant made by LawnDefender072003. It fires high-damaging missiles down its lane, exploding upon hitting a zombie that has lots of health. When approached, it drives down its lane, running over both zombies and plants, dealing 90 damage to zombies, and insta-kill damage for plants.

Strategy
Avoid letting zombies approach it because it may kill all of zombies but it also kill of of the plants, especially endangered ones.
