Who would want to eat zombies? Chomper would. The Chomper costs 150 sun and it eats any zombie in front or behind it, but it takes a while to chew its meal. Chompers are awesome for Pole Vaulting Zombies. Plant a Wall-nut in front and a Chomper behind. The Pole Vaulting Zombie jumps over the Wall-nut and gets eaten by the Chomper.
