Zombot Plank Walker

The Zombot Plank Walker is the boss of Pirate Seas in Plants vs. Zombies 2: It's About Time. It is controlled by Dr. Zomboss, and is battled in Pirate Seas Day 25. It somewhat resembles the Egyptian variation of Zombot with minor modifications.The fight was added in Version 2.0.1.

In the battle, it can summon all Pirate Seas Zombies except for the Pirate Zombie, Seagull Zombie, Swashbuckler Zombie, Flag Pirate Zombie, and the Imp Cannon; the last probably because it can fire Imp Pirate Zombies by itself. The plants given via the conveyor-belt are Kernel-pults, Snapdragons, Threepeaters, Coconut Cannons, Spikeweeds, and Cherry Bombs.

"Hoist the mizzemast, batten down the hatches! 15 zombies on a dead man's boat, yo ho ho and a bucket of brains!" Dr. Zomboss had to admit he was really getting into this whole pirate thing. Though he never thought he'd be on a boat on a boat.

Overview
The Zombot Plank Walker has an absorption of 1,375 normal damage shots, and its appearance changes at 458 and 917 normal damage shots, before dying at 1,375 normal damage shots.

Attacks
The Zombot Plank Walker randomly performs one of the following actions:
 * It will summon zombies:
 * first phase:
 * Conehead Pirate
 * Pirate Captain Zombie
 * second phase:
 * Conehead Pirate
 * Buckethead Pirate
 * Pirate Captain Zombie
 * Gargantuar Pirate
 * third phase:
 * Conehead Pirate
 * Buckethead Pirate
 * Pirate Captain Zombie
 * Barrel Roller Zombie
 * The "eye" will open and reveal a cannon. It will then fire seven Imp Pirate Zombies into the third or fourth column.
 * It will tap the ground, step back, and charge, destroying any plants and zombies in two rows; stopping near the Lawn Mowers and jumping back. As with the Zombot Sphinx-inator's similar attack, using Plant Food can prevent it. It will also stop and be stunned if it collides with a Cherry Bomb.
 * Although any Plant Food power-up will work, Spikeweed's is the least adviced to be used against this attack. Spikeweed's will pull the Zombot Plank Walker and stop it for a short while, although this is shorter than the period it would be stunned with other Plant Food power-ups. Also, that can be a bad idea since the Zombot will destroy your plants but not the zombies.
 * While using a Kernel-pult's Plant Food effect works most of the time to stop his charge attack, sometimes, especially in stage 3 of the health bar of the Zombot, it is unfazed by the catapult plant's Plant Food upgrade at all when he is doing his charge and will proceed to destroy plants from both lanes anyway. You have no idea when this will happen so be prepared.

Trivia

 * Dr. Zomboss has an eyepatch on his left eye just like a pirate.
 * Strangely enough, it is the same eye missing from his face for his hologram when the player defeats him.
 * The Zombot Plank Walker actually looks like a ship with cannons attached to it and anchors as its legs.
 * Before the battle starts, Dr. Zomboss suspected that Penny is also another possible creations of his Zombots.
 * This machine has a single eye just like the Egyptian Variation, Western Varation and the Future Variation which resembles a cyclops.
 * This and Zombot Dark Dragon are the only Zombots that don't launch missiles. The Zombot Plank Walker instead fires a barrage of Imps while the Zombot Dark Dragon breathes flames that could hatch Imp Dragon Zombies.
 * The battle with the Zombot Plank Walker is the only Pirate Seas level with planks on every lane.
 * If you will observe closely, the Imp that is tied up at the upper part of the eye of the Plank Walker is actually a dead one.
 * In the battle, some plants are only recieved numerically. You will only receive five Coconut Cannons and Threepeaters (because of the former's instant kill properties and the latter's three way projectiles) at a time. However if one dies, a new Threepeater/Coconut Cannon will appear.
 * Likewise, due to its destructive Plant Food ability, 2 Snapdragons will only be brought at a time while only 1 Cherry Bomb could be brought at a time.
 * However, Spikeweeds and Kernel-pults are extremely common and unnumerically unlimited, with the former being more common to appear.
 * Once you defeat the Zombot Plank Walker, a rainbow is seen above the level.
 * If you use Plant Food on a Spikeweed before it jumps it will teleport to where is it was jumping to.
 * The in-game Zombot Plank Walker has the letter "Z" on its flag, while some pictures don't.
 * This is the only Zombot that doesn't have two joysticks for Dr. Zomboss to control, instead, it's a steering wheel.
