Here’s the complete guide to applying Christmas Mutation on pets in Build a Zoo. Find out how to get the Christmas Mutation and what it does.
Build a Zoo Christmas Mutation Guide
The Christmas Mutation is a limited-time special mutation introduced with the Build a Zoo Christmas Event. If you’re working through the Day 1 quests, you’ll need to hatch five Christmas-mutated pets, and completing that task rewards you with 20 Christmas Hats. Because Christmas eggs are expensive and slow to hatch, knowing every method to get the mutation will save you a lot of time and currency. Below is a clean, easy-to-follow guide covering all ways to obtain the Christmas Mutation during the event.
How to Get Christmas-Mutated Pets
There are two reliable methods to obtain Christmas Mutation pets during the event period:
- Christmas-Mutated Eggs on the Conveyor Belt
- These eggs only appear during Christmas Weather, a new timed weather event that triggers randomly and lasts for five minutes.
- When active, your conveyor belt can spawn special eggs marked with a Santa Hat icon.
- These eggs cost 7.5× more than regular eggs and take 3.5× longer to hatch, so you’ll need a healthy amount of cash and may want to use Speed Hourglasses to finish your event quests on time.
- Yeti Eggs from the Christmas Event
- Open the Christmas Event menu and go to the Event Egg section.
- You can claim one free Yeti Egg every 30 minutes, up to six per day.
- Or use the latest Build a Zoo code for free Yeti Eggs(added on Dec 12)
- Each Yeti Egg has a 20% chance to hatch as a Christmas Mutation.
- This is the cheapest method overall, especially if you’re patient with the timers.
Why Christmas Mutations Matter
Christmas-mutated pets earn 15× more income than their normal versions, making them incredibly valuable for long-term zoo progression. Even a small collection of Christmas pets can boost your cash generation dramatically.
How to Give Big Pets the Christmas Mutation
Big Pets can also gain the Christmas Mutation, but they require a special item:
- Use a Candy Cane, a Mythical Food that has a chance to apply the Christmas Mutation to a Big Pet.
- Candy Canes can be purchased from the Christmas Event Shop for 400 Hats, or from the Food Shop for 80B.
- Applying one doesn’t guarantee the mutation, so you may need multiple attempts depending on your luck.
If you want to finish your Day 1 objectives quickly, combine conveyor eggs during Christmas Weather with steady Yeti Egg claims. This gives you the best mix of speed and affordability while still securing your Christmas Hats efficiently.
