How to Get Chicken Zombie in Grow a Garden – Zombified Mutation Pet Guide

The Chicken Zombie is one of the most valuable event pets in Grow a Garden Roblox, introduced during the Blood Moon event.

It comes with a powerful passive ability that gives your fruit one of the rarest boosts in the game—Zombified Mutation.

Here’s how to unlock it and why it’s worth keeping in your farm.

How to Get Chicken Zombie

This pet is only available during an active Blood Moon event.

To obtain it:

Log into the game while the Blood Moon is running
Watch the automatic cutscene: a zombie jumps on your chicken, attacks Wise Owl, and transforms the pet
Once the animation ends, Chicken Zombie is added to your pet inventory for free

You don’t need to purchase or hatch it—it’s entirely event-based and cannot be bought from shops.

If you missed the cutscene, try rejoining a Blood Moon server and wait for the script to trigger again.

Every 29.46 minutes, the Chicken Zombie has a 20.27% chance to apply a Zombified Mutation to one random fruit in your garden.

The Zombified Mutation drastically boosts the value of that fruit—up to 25x its normal sell price.

This makes it one of the best passive income tools, especially for large gardens with many fruit-producing plants.

The effect is automatic and works in the background while you’re playing or farming normally.

You can level up Chicken Zombie by feeding it mutated fruits.

Here are some of the best fruit types to use:

Feeding these will raise the pet’s XP and unlock additional effects or mutation slots.

Higher level = better activation rates and stronger passive farming performance.

Place high-value crops like Eggplant or Melon in active grow zones
Combine Chicken Zombie with Bloodlit or Celestial Mutations for multi-layered fruit bonuses
Don’t AFK too far—mutation requires some player activity to stay consistent
Use tools like Harvest Tool to collect the high-value fruits quickly

If you log in often during Blood Moon, you’ll benefit greatly over time from this mutation cycle.

The Chicken Zombie is a free but powerful pet that only appears during Blood Moon events.

Its passive Zombified Mutation makes it a core farming tool for serious Grow a Garden players.

If you haven’t claimed it yet, don’t miss the next Blood Moon window—this pet won’t always be available.
