Realization zombie

This zombie isn't very special, it is your typical everyday zombie, but it realised one thing, why arrive from that side of the lawn?

It appears from either the top or the bottom of the screen, hopping over the fence, making things like explosives and cattails neccecary, they then proceed to travel across the top/bottom lane, usually passing your nut-barricade.

Because they are regular zombies they "Can" have cones and buckets, however this is very unlikely.
