im pretty sure this river is called collin river or something. well thats what the file said when i tried to download it. But anyway! Heres how these plants protect the river: Lily pad: Without lilypads, it would be almost impossible to defend this river! Cattails: A powerful upgrade to the lilypad and the main defender of the river! Great for getting zombies. Wallnuts: these help stall the zombies when zombies attack! Tangle kelps: When a zombie comes and the zombie is simply to far for a cattail to hit, tangle kelp is here to save the day! and if they get hungry, they dont mind chowing down on fish!
