Strategies
The Zombie Bull will be difficult to take out without the Tall-nut. First, you must let it lose its Zombie Bull Rider and then kill it. That will make the Zombie Bull slow down. Use an instant kill to destroy it in one hit. Just remember that the Zombie Bull's health is same as the Buckethead Zombie's health, as they both take 65 shots. You can delay/destroy a Zombie Bull with any one use plant (Potato Mine, etc.) or freezing them with an Iceberg Lettuce. You can also use Kernel-pults to delay the Zombie Bull to stun it.

Multiple Zombie Bulls will attack the player in Big Bad Butte. Use empty mine carts to your advantage. Take the opportunity while you are building your sun production especially in higher levels, a tendency of a Zombie Bull coming after killing the first Cowboy Zombie is approximately at 20%. Other than that use Tall-nut if it's just alone or accompanied by any zombie.

These and the Wild West Gargantuars are very dangerous. With the Gargantuar's toughness and the Zombie Bull's speed can be of troublesome. You will require to keep a Cherry Bomb and Blover at your disposal.

Trivia

 * 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 a member of the "Zombie side".
 * In a way, it is a down-graded version of the Gargantuar with the Pole Vaulting Zombie's weakness.
 * This is because while the bull has a high amount of health similar to the Gargantuar, it will throw its Zombie Bull Rider when it meets a plant as opposed to crushing them.
 * However, it is killed instantly when blown up by a Potato Mine, Jalapeno, and Cherry Bomb.
 * There is a bug which the Zombie Bull will launch its Zombie Bull Rider when meeting an empty minecart.
 * If it meets an armed Potato Mine, it will disappear upon contact with its explosion.
 * The same goes when it encounters a Lawn Mower.
 * This is because it doesn't have a beheading animation.
 * Also, you will also hear throughout the level the Zombie Bull Rider screaming if this ever happens.
 * 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 by Lightning Reeds or Power Zap, Zombie Bull Riders vanish in the process.
 * It lost immunity to Chili Bean in the 2.1 update. This may prove it's a cyborg, and not a robot, like it says in the almanac. It is unknown why it has lost its immunity to Chili Bean.
 * This and Treasure Yeti completely freezes when disabled by E.M.Peach because unlike the zombies in Far Future who have animation, this and Treasure Yeti don't have.
 * Zombie Bull, Gargantuar Prime and Treasure yeti are the only zombies that are cyborgs/robots
