Petrified Trunk Roller (PvZ2)

Petrified Trunk Roller is a fan-made zombie encountered in Plants vs. Zombies 2, mainly seen in Permian Climax

He will push forward a large petrified log, protecting him from straight shots. It also won't conduct electricity, will block splash damage, will stop Snapdragon's flames, absorb Phat Beet's shockwave and even block piercing attacks like those of Cactus, Fume Shroom and Laser Bean. Underground plants will be instantly crushed, dealing 1000 damage to the trunk. The trunk also cannot be pushed back by any mean, but doesn't allow the zombie to access tunnels because of this.

Origins and appearance
He isn't based on any peculiar zombie, but the skin he wears and the glove/boot-like clothes may give hint towards potentially a cynodont He is overall similar to the Barrel Roller Zombie, but he uses a petrified trunk, grey/brown, probably from a Carboniferous tree

Overview
He can support up to 250 damage, with his arm falling after taking 150 damage. The trunk, on the other hand, has 3500 HP, but will start degrading at 2750, 2000, 1000 and 500 damage taken

Strategies
He is one of the major threats of Permian Climax, being even more threatening than a Gargantuar ; while he won't throw an Imp, he has technically more HP, and cannot be stalled by placing plants to push him back or buy some time. The only way to attack him is either by using backward-shooting plants, but this is highly unrecommended, or to use plants like catapults, whose shots will target him first. Breaking his trunk actually require as much damage as what is needed to kill a Gargantuar, so if you cannot afford lobbed-shots plants, you will have to keep enough firepower to shut him down or even two instant-kills. The best strategy is simply to rely on something that you can use normally in Permian levels, like a powered Dusk Lobber, or a Pultaspermum, because both have good crow control abilities and will be useful with other zombies. Melon-Pults are clearly too expensive, Pepper-Pult suffers from a general lack of good splash damage, while both Kernel-Pult and Cabbage-Pult are too weak to be used and will generally be a waste of space. The other tactic is to use a Shrinking Violet ; this can be especially useful if there is many of them, and will make unable to continue with his trunk. In most cases, you will still have to deal with the trunk they left, but thankfully, you can simply ignore it.
