Zombeast

Zombeast is a zombie in Plants vs. Zombies 2. He could ram and bite a plant one tile away from the plant, degrading/instantly killing the plant. When he tries to ram and bite a plant who executes its PF effect, Zombeast will be stunned for 2 seconds, then he'll roar, pushing all plants ahead of it to the left 1 tile and behind it to the right 1 tile and pushing zombies to the left for zombies ahead of it and to the right for zombies behind it.
