Pet Mutations arrived with Update 9 in Build a Ring Farm, adding a permanent passive bonus on top of a pet’s normal ability. Each mutation changes one specific stat, from shorter ability cooldowns to higher farm earnings, and every pet can roll one of six results from the Pet Mutation Machine.
Quick answer: Equip a level 50 pet, walk to the Pet Mutation Machine in the center of the map, press E, choose INSERT A PET, wait for the timer, then press Claim to receive your mutated pet.
All pet mutations, odds, and effects
There are six pet mutations, and all of them come from the same machine. The rarer a mutation is, the stronger its effect, but the two rarest results also carry a trade-off. Astral shortens cooldowns while adding farm earnings, and Godly gives the largest ability boost at the cost of a small earnings penalty.
| Mutation | Chance | Effect |
|---|---|---|
 Charged | 46% | Pet Ability Cooldown: -5% |
 Sprout | 28% | Sprinkler Power: +7.5% |
 Rooted | 16% | Saw Yield: +10% |
 Royal | 7.5% | Pet Ability Boost: +15% |
 Astral | 2.4% | Farm Earnings: +3%; Pet Ability Cooldown: -5% |
 Godly | 0.10% | Pet Ability Boost: +25%; Farm Earnings: -5% |
Requirements before you can mutate a pet
Two conditions gate access to pet mutations, and the machine will not accept a pet until both are met.
- Unlock Floor 3 of your garden. The Pet Mutation Machine cannot be used until Floor 3 is open.
- Bring a level 50 pet. Only pets at level 50 can receive a mutation, so lower-level pets will not qualify.
The machine sits in the middle of the map, directly across from the Friend O. Tron machine used for rare seeds. Once Floor 3 is unlocked, you can approach it and begin.
How to apply a mutation at the Pet Mutation Machine
You know it worked when the Claim button returns the pet with a mutation label attached and its listed stat bonus active. The result is random, weighted toward the common Charged and Sprout outcomes, so reaching Astral or Godly usually takes repeated attempts.
