Lystrosaur Zombie (PvZ2)

Lystrosaur Zombie is a fan-made zombie encountered in Plants vs. Zombies 2, mainly in Permian Climax

He will first be seen digging quickly towards your plants, stopping only to eat low plants like Spikeweeds. When he reaches a normal plant, he will pop out of the ground and start eating it, proceeding like normal zombies afterward. They can appear during the ambush Collapsing Tunnels !, where they will random pop out of the ground on tiles from the 4th to the 9th column.

Origins and appearance
This zombie is based on the Lystrosaurus, a large herbivorous dicynodont known for its fossorial habits. It is also one of the few animals known to have survived the Permian extinction. He looks like your average primal zombie, with quite a lot of hair. He is dressed with lystrosaurus skin, has claws stitched on his arms and a skull as a helmet

Overview
He can support up to 450 damage, but his helmet will be weathered after suffering from 250 damage and his arm will fall off after taking 350 damage

Strategies
This zombie is one of the major threat of Permian Climax ; while he won't protect other zombie, he will forbid any use of Spikeweeds, Spikerocks or Celery Stalkers, and can't be hurt until he get to the surface. There is two main strategies to get rid of him : first, you can use cheap plants like Puff-Shrooms and Stallia (Iceberg Lettuce will simply be used without doing anything) to force him to get to the surface, leaving your defenses to kill him and generally making this easier, or you can try to set up a defense with defensive plants to make him surface without harming your other plants ; this is generally useful to deal with a lot of them, but they will absorb most of the damage and can render plants with splash damage less useful. Burniadia is especially useful, as the projectiles will still be able to hit ennemies behind and he can do a decent amount of damage to him
