Headcrab Invasion Addon

Go to files

Adds multiple headcrab variants and infected zombie types that spawn naturally—fast, poison, and zombified mobs for thrilling new encounters in Minecraft.

Let's start now with these crabs. Maybe you know what they will do when they find their prey: jump on their heads and turn them into zombies.

The Headcrabs

Standard Headcrab — Health 8, Damage 2–3. Slow and easy to hit.
Fast Headcrab — Health 8, Damage 3–4. Fast and harder to hit.
Poison Headcrab — Health 9, Damage 2–4. Sometimes bites and causes poison; slow and easier to hit.
Headcrabs can spawn naturally in the Overworld. Standard Headcrabs can also spawn in the Nether.

The Zombies

Standard Zombie — Health 20, Damage 3–4. Can spawn in caves or at night.
Villager Headcrab Zombie — Health 18, Damage 3. Appears when a villager is killed by a headcrab.
Piglin Zombie — Health 18, Damage 3. Appears when a Piglin is killed by a headcrab.

Fast Zombie

Fast Zombie — Health 16, Damage 3–5. Can move fast.
Can spawn at night or in dark places.

Poison Zombie

Poison Zombie has 2 stages: Beginning of Infection and End of Infection. In the final stage, 2 Poison Headcrabs will appear on its back.
Beginning stage — Health 22, Damage 2 with poison.
End stage — Health 26, Damage 3 with poison.
Be careful with this zombie.

Zombider (Zombie Spider)

Created when a Standard Headcrab latches onto a spider's head.
Can climb and move fast like Fast Headcrabs and Fast Zombies but is weaker.
Health 10, Damage 4–6.
