Zombie Bull is the eleventh zombie encountered in Wild West in Plants vs. Zombies 2. He charges towards the player's plants and launches the Zombie Bull Rider off its back once it approaches a plant. Zombie Bull runs first at full speed, then slows down upon throwing the Zombie Bull Rider riding it.
Can launch his zombie rider past most of your defenses.
Special: launches a low flying imp rider over plants
Weakness: Tall-nut blocks flying imp
He's not an angry bull. He loves flowers, playing in the fields, sitting in the trees, and long walks across the pasture. He wants to settle down when he meets the right cow. Too bad he's a robot.
Zombie Bull absorbs 70 normal damage shots, and its appearance changes upon absorbing 23.5 and 47 before dying at 70 normal damage shots. Zombie Bull also eats plants at a 1.5x faster rate than an average Basic Zombie.
The Zombie Bull will be difficult to take out without the Tall-nut. You can either make it toss its Zombie Bull Rider by placing cheap plants next to it (Potato Mine, Puff-shroom) first to slow down the Bull, then kill it. It will not toss its Zombie Bull Rider if it encounters an underground plant such as Spikeweed and Celery Stalker. Or you can use an instant kill to destroy it before it loses its rider to take both out. In dire times, the player can Plant Food on an Infi-nut, whose Force field will act as a Tall-nut that covers all lanes.
It can also be stunned by an E.M.Peach because it is actually a robot, instead of a biological animal. Zombie Bulls can be destroyed with any one use plant (Potato Mine, etc.), frozen with an Iceberg Lettuce, and/or delayed by Sap-fling, Power Snow, butter from Kernel-pult, Snow Pea and Winter Melon.
Multiple Zombie Bulls will attack the player in Big Bad Butte. Use the empty minecarts to your advantage. Take the opportunity while you are building your sun production especially in higher levels, as a tendency of a Zombie Bull coming after killing the first Cowboy Zombie is approximately at 20%. Other than that, use a Tall-nut if it is just alone or accompanied by any zombie. Stunions can come in handy as well to provide some time to forcibly throw its Zombie Bull Rider.
These and the Wild West Gargantuars are very dangerous. With it and the Zombie Bull's speed can be of troublesome. It is recommended to have either a Cherry Bomb or a Blover at your disposal. If you can move a cart into the same row, you can put one of the plants from above on the cart to deal with it or a defensive plant like Infi-nut, Sweet Potato, etc. that you can move around forcing it throw the rider and halt its speed.
If you have not selected a plant like this, your last resort is a lawn mower or planting a random plant (besides Spikeweed and Spikerock), in front of the Zombie Bull to spare time in killing both Zombie Bull Rider and the Zombie Bull.
Beware as it can throw its Zombie Bull Rider over the edge of your side, if it is close enough and you have missing lawn mowers, it can lead you to your defeat. To counter this, use Hurrikale or Power Ups to push back or kill the Imp with ease.
- Zombie Bull, Rodeo Legend Zombie, Mechanical Wolf Zombie (Or Hound Bot Zombie) and Parrot Pal are the only robot animals in the whole series.
Specific to Plants vs. Zombies 2
- Even though it is called a "Zombie Bull," it is described as and shown to be a robot. Though it might have got its name because it is affiliated with zombies.
- There was a bug which the Zombie Bull will launch its Zombie Bull Rider when meeting an empty minecart. It was fixed in the 2.3 update.
- In the 6th step of Snow Pea's Epic Quest, Zombie Bulls coming by sandstorm move the same speed as if they have thrown Zombie Bull Riders but strangely never even rush or have thrown the Zombie Bull Riders.
- If it met an armed Potato Mine, it would disappear upon contact for explosion. As of the 2.2 update, it was fixed, so the Zombie Bull dies regularly instead. The same goes when it triggers a lawn mower. This is because it does not have a beheading animation.
- The Bull Rider can keep laughing if the Zombie Bull with the Imp is shrunken, which also shrinks the Imp.
- If a Zombie Bull dies before it releases its Zombie Bull Rider, the Zombie Bull Rider will die along with it.
- If it gets zapped while it still has its Zombie Bull Rider by Lightning Reeds or Power Zap, Zombie Bull Rider vanishes in the process.
- It lost its immunity to Chili Bean in the 2.1 update. This may prove it is a cyborg, and not a robot, like it says in the Almanac.
- Zombie Bull and Treasure Yeti completely freeze when disabled by E.M.Peach because unlike the zombies in Far Future who have an animation when disabled, this and the Treasure Yeti do not have one.
- Zombie Bull may be a reference to the Terminator films, as when it is degraded enough, its face resembles the face of a T-800.
- Citron's Plant Food attack does not stop on the Zombie Bull unlike other machines.
- It is one of the four zombies recognized as different life forms at a guise of a zombie. The others are Zomboni, Baron von Bats and Treasure Yeti.
- It is similar to the horse the Cavalry Zombie rides, as well as the Mechanical Wolf Zombie since they all charge the player's defenses with the same or similar gimmicks.
- In themed Piñata Parties, Zombie Bulls will throw Zombie Bull Riders, but they will turn into specialized Imps almost instantly after they are thrown.
- This may be a glitch.
- In The Mine Cart, when the vase with a Zombie Bull is open, the Zombie Bull Rider will fly to the rightmost of the screen. The Zombie Bull Rider will then enter the lawn normally with its bull.
- Before the 5.7.1 update, it was one of the zombies that did not have a repeatable quest for it in the Travel Log.
- When it throws a Zombie Bull Rider after it reaches a certain column of the lawn, there is a chance that the lawn mower will not activate and the said zombie will eat the player's brains. This is similar to how the Dancing Zombie summons a Backup Dancer behind the lawn mower in the original game.
- In version 5.9.1 of the international version, if the Zombie Bull ate a Hypno-shroom, it would be restored back to full health and then threw its hypnotized imp backwards. If the imp was thrown backwards from the second column from the player's house, the player would instantly lose the level.
- It it similiar to the Cavalry Zombie. Both of them are animal-like zombie that carry another zombie on their backs and launch them when encountering a plant.
