|First seen||Frostbite Caves - Day 8|
|One day, a Cave Zombie fell head-first into a glacial stream. It had been a bad day already, so he lay there in the frigid water for a long time contemplating the insignificance of his life. When he finally stood up, he discovered that his head was encased in ice. At last, his life had meaning! He was unique! He was Blockhead Zombie! At least, that's his story and he's sticking to it.|
Blockhead Zombie is the eighth zombie encountered in Frostbite Caves in Plants vs. Zombies 2. Like Knight Zombie in Dark Ages and Jurassic Fossilhead in Jurassic Marsh, it does not have a special ability. Instead, its only purpose is to absorb a large amount of damage from plants and protect zombies behind it. Despite having headwear made of ice, it does not have any weakness to fire-based projectiles, such as flaming peppers, fire peas, and napalm peas. In fact, the Hot Potato cannot be used as well to defrost the headwear.
The Blockhead Zombie has a rugged, protective ice block on his head that covers most of its face. Its attire and facial hair is the same as a standard Cave Zombie's.
The ice block on his head provides amazing protection from damage.

Blockhead Zombie absorbs 89.25 normal damage shots and its appearance changes upon absorbing 27, 54, 80 (when the ice block is destroyed), and 84.75 normal damage shots before dying at 89.25 normal damage shots.
Although Blockhead Zombie has moderate speed, its ice block absorbs a lot of damage, which means this zombie is very strong. Like its counterpart, Knight Zombie, it can be a big problem if you are unprepared. If you see it in the seed selection screen, use a Potato Mine, Toadstool, Chili Bean, Squash, or Chomper to kill it instantly, because Blockhead Zombies are harder to destroy than Buckethead Zombies. If combined with Hunter Zombies and Dodo Rider Zombies, they can be very threatening. Avoid using Magnet-shrooms, unlike Knight Zombie's helm, the ice block is not magnetic, thus wasting 100 sun and a seed slot in the process. If the premium seed slot expansion is purchased, this will aid the player greatly. It can allow another high-damage plant, such as Cherry Bomb, Jalapeno, or Squash. Beware, if there is a zombie in front, Squash might not register which zombie you want to kill. Also, be sure to stock up on plenty of coins by the Endless Zones or the levels you previously played in order to use Power Ups to kill this zombie in a final attempt to defend your house.
Using Sun Bean on this zombie is a very good idea. It is best to use Plant Food on the Sun Bean to kill it instantly because you could get a lot of sun from this zombie and ice blocks give more sun when destroyed than buckets.
Among all the plants released in Frostbite Caves, Chard Guard is the most effective against this zombie, as it can hurl it and other zombies back, buying your defenses time. If you want to use Chard Guard against him, it is recommended to have high damage plants behind the Chard Guard, to deal damage while Chard Guard flings back Blockhead Zombie. Pepper-pult can also be used against this zombie, but the peppers will not deal more damage, even though they are on fire and the Blockhead Zombie's protection is made of ice.
- It might have been inspired by Ice Block Zombie from Frostbite Falls in Plants vs. Zombies Adventures. It shares this trait with Fire Peashooter, which might have been inspired by Flaming Pea.
- Blockhead Zombie, Conehead Zombie, Buckethead Zombie, Camel Zombies, Admiral Helmet Zombie, Knight Zombie, Bug Zombie, and Jurassic Fossilhead are the only zombies that can degrade into their respective Basic Zombie variant.
- The word "blockhead" is used to describe one who is not very intelligent, which may explain why he falls into a glacial stream as said in the almanac.
