Mutations Guide
Silver 1.2× through Rainbow 3.5×, Spirit Bloom, Enchanted, Nitro, Spectral shards (500 Souls, 25%, 2.75×), Parasite, and shop variants — how each roll changes pen income.
Mutations overview
Mutations raise pen income on top of a pet's Index base and any size roll. Silver, Gold, and Rainbow can land on map hatches or Fuse. Bloom and Spirit Bloom come from the Sakura Incubator. Enchanted is Update #7 Essence. Nitro is Update #8 Racing. Spectral is Update #9 Phantom Express Soul Extractor shards (500 Souls, 25% apply, 2.75×). Parasite is 3× from Hungry Frog. Rainbow tops the ladder at 3.5×. Zombified is the Halloween Egg store re-roll.
Mutation multiplier table
Index multipliers stack on a pet's base income before size and weight. Silver 1.2×, Bloom 1.25×, Gold 2.5×, Spirit Bloom 2.5×, Fractured / Scrambled / Nitro / Spectral / Enchanted 2.75×, Parasite 3×, Rainbow 3.5×. Mecha, Luminous, Skeletal, and Zombified are shop or event visual variants. Final pen cash still scales with pet size.
Multipliers apply after the pet's size-adjusted base. Final pen cash still scales with weight on top of these figures.

- Larger or off-color eggs in a nest carry a mutation. Compare against neighboring eggs before you grab one
- The Fuse machine sits on the left side of the starting area, before you enter the biomes. Feed three of the same species
- Pets that already earn above their Index base improve Silver, Gold, and Rainbow luck on Fuse. Skip feeding three weak commons when you have a strong donor
- Rainbow is the top natural hatch multiplier at 3.5×. Spirit Bloom is the top Sakura Incubator roll at 2.5×
- Charge Sakura eggs to 150% when you are chasing Spirit Bloom; higher charge improves the rare outcome but does not guarantee it
- Silver, Gold, or Rainbow eggs can still enter the Sakura Incubator; Bloom or Spirit Bloom can stack on that roll
- Fractured is bought with Boss Tokens after clearing map Rifts (10% apply), not rolled from Sakura or map nests
- Scrambled came from the Update #5 Experiment Shop. Buy it with Samples and use it on an unhatched egg for a 10% apply chance while that shop was live
- Parasite came from Hungry Frog Parasite Eggs (~1.5%). Monstrous only applied to Titan Temple pets from Monster Chests (both ended Sep 5, 2026)
- Mecha, Luminous, Skeletal, and Zombified are shop or event visual variants with their own Index rows — not the 1.2×–3.5× income ladder above
- Do not fuse pets carrying Rainbow, Spirit Bloom, Enchanted, Nitro, Spectral, Fractured, Scrambled, Parasite, Monstrous, Mecha, Luminous, Zombified, or Skeletal unless you accept losing the variant on the output
- Enchanted Essence is crafted in the Enchanted Tree from Emerald, Sapphire, Amethyst, and Radiant butterflies; apply chance is 100% at 2.75×
- Nitro is bought with Racing trophies; apply chance is 10% on an unhatched pen egg at 2.75×
- Spectral: board Phantom Express, vacuum Lost / Haunted / Vengeful spirits (and Ghouler boss), trade 500 Souls for a Spectral Mutation Shard, apply for 25% at 2.75×
- Zombified pets come from the Halloween Egg Re-Roll in the Robux shop, not from map nests
- A mutated mid-tier species can out-earn a plain pet from a higher rarity

Craft Enchanted Essence in the Enchanted Tree from Butterfly Bloom catches. Apply to an unhatched pen egg for 2.75× with a 100% success rate.

- Equip the Net and run through Emerald, Sapphire, Amethyst, and Radiant butterflies in Enchanted Forest.
- Trade butterflies up at Convert, or spend a full set at the Enchanted Mutation Shrine for Enchanted Essence.

Sakura Incubator
The Sakura Incubator sits at the back of Cherry Blossom. Offer a Crane pet once to unlock it permanently, then charge inventory eggs with Sakura Crystals from the Great Bloom event for Bloom (1.25×) or Spirit Bloom (2.5×).
Unlock steps
How to unlock the Sakura Incubator once Cherry Blossom is reachable.
- Hatch a Crane from a Cherry Blossom nest egg (plan for 3.5B Speed on the steal, above the 2.5B gate readout)
- Target the common Epic look: pink-topped shell with dark purple bands around the middle. Crane is the most common Cherry Blossom Epic
- Carry the Crane to the Sakura Incubator at the end of the zone
- Submit the Crane, the unlock is permanent, but that pet is consumed
- Hatch another Crane later if you need a fresh one; size and mutations on the offer do not matter
Great Bloom event
Great Bloom crystal notes tied to the Sakura loop.
- Runs on server time every 30 minutes in Cherry Blossom
- Lasts three minutes; stay in-zone before the notification so you do not waste travel time
- After unlock, a timer above the Sakura Incubator shows when the next Great Bloom starts
- Crystal Cherry Blossom Trees spawn; equip your bat and hit them for Sakura Crystals
- Farm crystals during the window; you need a large stack before mutating high-tier eggs
Mutating eggs
Rules for which eggs can take Bloom / Spirit Bloom in the incubator.
- Place an egg from your inventory into the unlocked Incubator (hatched pets cannot be mutated here)
- Eggs that already show Silver, Gold, or Rainbow can still go in; Bloom or Spirit Bloom can stack on top of that regular mutation
- Deposit Sakura Crystals to fill the charge meter
- At 100% charge the egg mutates: 97.5% Bloom (1.25×), 2.5% Spirit Bloom (2.5×) on that roll
- Charge to 150% (max) when you are hunting Spirit Bloom; higher charge improves the rare outcome but does not guarantee it
- 1,000 crystals fills a 100% charge on many eggs; 1,500 crystals pushes toward the 150% max charge when chasing Spirit Bloom
| Mutation | Detail |
|---|---|
| Bloom | Common Incubator roll (~97.5% at 100% charge); 1.25× Index multiplier |
| Spirit Bloom | Rare Incubator roll (~2.5% at 100% charge); 2.5× Index multiplier; chase at 150% charge |
FAQ
Which mutations can hatch from map eggs?
Silver, Gold, and Rainbow can appear when you hatch a map egg, or when you run three matching pets through Fuse. Bloom and Spirit Bloom need the Sakura Incubator.
Where is the Fuse machine?
On the left side of the starting area, before the biome gates. You need three pets of the same type. Stronger income donors raise the chance of Silver, Gold, or Rainbow on the output. Fusing three pets that already share a mutation keeps that mutation.
What are the income multipliers?
Silver 1.2×, Bloom 1.25×, Gold 2.5×, Spirit Bloom 2.5×, Fractured / Scrambled / Nitro / Spectral / Enchanted 2.75×, Parasite 3×, Rainbow 3.5×. Final pen cash still scales with pet size and weight.
What is the strongest mutation?
Rainbow is the highest income multiplier at 3.5×. Parasite is 3× from Hungry Frog (ended). Spirit Bloom is the top Sakura Incubator roll at 2.5×. Enchanted, Nitro, Spectral, Fractured, and Scrambled share 2.75× with different apply rates.
How do I get Scrambled?
Scrambled was an Update #5 Experiment Shop tube bought with Samples (through September 26, 2026). Apply it to an unhatched pen egg for a 10% chance at 2.75×. That shop closed with the Update #6 cutover; existing Scrambled pets keep the mutation.
How do I get Parasite?
During Hungry Frog (Aug 29 to Sep 5, 2026), feed five infected eggs to the frog for a ~1.5% chance at a Parasite Egg. Hatch it for the 3× Parasite mutation. New drops ended with that event.
Is Monstrous still available?
No new Monstrous rolls. The Hungry Frog Monster Chest window ran Aug 29 to Sep 5, 2026. Pets that already have Monstrous keep it.
How do I get Enchanted?
Unlock the Enchanted Tree via Wisp quests, grab the Butterfly Net, catch butterflies during Butterfly Bloom, craft Enchanted Essence at the shrine (240 Emerald / 115 Sapphire / 40 Amethyst / 1 Radiant), and apply it to an unhatched pen egg. Application succeeds 100% of the time at 2.75×.
How do I get Spectral?
Finish Echo's Memories for your first Phantom Express Ticket, board on the hour or half-hour, vacuum spirits for Souls (Lost 20, Haunted 50, Vengeful 110, Ghouler up to 2,500 split across players), trade 500 Souls at the Soul Extractor for a Spectral Mutation Shard, then apply it to an egg for a 25% chance at 2.75×.
How do I get Nitro?
Win Nitro Races for trophies, buy the Nitro consumable in the Racing shop, and apply it to an unhatched pen egg for a 10% chance at 2.75×.
How do I get Fractured?
Clear map Rift Overlord fights for Boss Tokens, buy the Fractured consumable in the Boss Shop, and apply it to an egg for a 10% chance at 2.75×.
What is Zombified?
A rare re-roll on the Robux Halloween Egg. It produces Zombified versions of the six base Halloween store pets. It is a shop variant, not one of the 1.2×–3.5× income multipliers.
How do I recognize a Crane egg?
In Cherry Blossom, look for a pink-topped egg with dark purple bands through the middle. Crane is Epic at $4K/s and the most common Epic hatch from that biome.
Do I lose my Crane after unlocking the Incubator?
Yes. The Crane is consumed when you submit it. The machine stays unlocked forever, hatch another Cherry Blossom egg when you need a replacement.
Can I mutate eggs already in my garden pens?
No. Pull the egg into your inventory first, then load it into the Sakura Incubator. Mutations apply before you hatch.
How many Sakura Crystals do I need?
1,000 crystals fills 100% charge on many eggs. 1,500 crystals pushes the meter toward 150% when you chase Spirit Bloom. Watch the Incubator meter before you commit.
How often is Great Bloom?
Every 30 minutes on server time, with a three-minute crystal farming window. After you unlock the Incubator, read the timer above the machine for the next start, and wait in Cherry Blossom before the alert so you can bat trees immediately.
Can I Sakura-mutate an egg that already has Silver, Gold, or Rainbow?
Yes. Load that unhatched egg into the Incubator as usual. Bloom or Spirit Bloom can apply on top of the regular mutation you already see on the shell.
