Mutations can change how a pet performs in Steal an Egg, but the final displayed MPS may also vary between pet instances with different Size or Weight. This guide compares the current Mutation set, commonly reported multipliers, acquisition routes and the evidence behind those numbers—without treating incomplete community data as an official formula.
Current major guides consistently list five Steal an Egg mutations: Silver, Golden, Rainbow, Bloom and Spirit Bloom. The commonly reported multiplier order is Spirit Bloom 3x → Rainbow 2.5x → Golden 2x → Bloom 1.5x → Silver 1.25x. Silver, Golden and Rainbow can appear on normal egg spawns or during Admin Abuse, while Bloom and Spirit Bloom come from the Sakura Incubator.
All Steal an Egg Mutations & Multipliers
The current Steal an Egg mutation pool is commonly reported as five variants. The first three are spawn-based mutations, while the two Bloom variants are tied to the Sakura Incubator.
| Mutation | Current Reported Multiplier | How to Get | Reported Chance | LOLGA Data Status |
|---|---|---|---|---|
| Silver | 1.25x | Egg spawn / Admin Abuse | Exact chance not reliably published | Needs LOLGA Test |
| Golden | 2x | Egg spawn / Admin Abuse | Exact chance not reliably published | Needs LOLGA Test |
| Rainbow | 2.5x | Egg spawn / Admin Abuse | Exact chance not reliably published | Priority Test |
| Bloom | 1.5x | Sakura Incubator | 97.5% current reported Incubator outcome | Current Guide Data |
| Spirit Bloom | 3x | Sakura Incubator | 2.5% current reported Incubator outcome | Current Guide Data |
What Actually Determines Pet MPS?
A mutation is only one part of a Steal an Egg pet's displayed information. Current in-game and screenshot-based records show that individual pets can also have Size, Weight, Gender and Personality, while the final earning result is displayed as Money per Second (MPS).
That does not mean every visible field is proven to change MPS. The important distinction is between a property that exists and a property with a confirmed income formula.
| Pet Data Field | Confirmed as a Pet Property? | Proven to Affect MPS? | LOLGA Interpretation |
|---|---|---|---|
| Pet Species | Yes | Yes / baseline differs by pet | Use as the starting point for any comparison. |
| Mutation | Yes | Strongly associated, exact formula still needs controlled verification | Core subject of this guide. |
| Size | Yes | Likely relevant | Keep separate from Weight and Mutation. |
| Weight | Yes | Likely relevant, exact formula unknown | Do not compare two pets if their weights differ substantially. |
| Gender | Yes | Not established | Visible property, but no reliable MPS effect should be claimed yet. |
| Personality | Yes | Not established | Examples include Energetic, Extremely Energetic and Lazy. |
| Income / MPS | Yes | Output value | Treat this as the final displayed result, not an input variable. |
Mutation Data Confidence: What We Know vs What Is Still Unclear
LOLGA separates high-confidence game information from values that are still based on community reporting. This helps readers see which parts of the Mutation system are well supported and which still need better evidence.
| Claim | Evidence Level | LOLGA Conclusion |
|---|---|---|
| Silver, Golden, Rainbow, Bloom and Spirit Bloom exist | High | Safe to publish as the current Mutation set. |
| Bloom and Spirit Bloom come from Sakura Incubator | High | Safe to publish as the current Sakura mutation route. |
| Bloom 97.5% / Spirit Bloom 2.5% | Current Guide / UI Data | Useful now, but update-sensitive. |
| Silver 1.25x / Golden 2x / Rainbow 2.5x | Community-Reported | Do not describe as an official developer formula. |
| Bloom 1.5x / Spirit Bloom 3x | Community-Reported | Needs controlled before-and-after data for independent verification. |
| Gender directly changes MPS | No Reliable Evidence | Do not claim an income effect. |
| Personality directly changes MPS | No Reliable Evidence | Do not claim an income effect. |
| Exact Weight → MPS formula | Unknown | Do not reverse-engineer a formula from partial screenshots. |
Why Mutation Multipliers Are Hard to Verify
Community screenshots often show a pet's income, mutation and some visible traits, but many do not show the complete combination of Size, Weight, Gender and Personality. That makes uncontrolled comparisons easy to misread.
For that reason, LOLGA treats the current mutation multiplier table as community-reported reference data until controlled comparisons become available. Cross-source agreement is useful evidence, but it is not the same as a published in-game formula.
LOLGA Research Status
What Are Mutations in Steal an Egg?
Mutations are special variants that can appear on eggs or be applied through a mutation system. Current guides describe them as modifiers that affect a pet's displayed income, which is why the same pet species can be much more valuable when it carries a stronger mutation.
Mutation and pet size are separate properties. A pet can have a mutation while also having a different weight or size roll, so you should not compare two pets only by mutation name if their other stats are different.
What Is the Best Mutation in Steal an Egg?
Based on the multiplier values currently reported by multiple August 2026 guides, Spirit Bloom ranks first at 3x, followed by Rainbow at 2.5x. This ranking will be updated if LOLGA's own MPS tests produce a different result.
How to Get Mutations in Steal an Egg
There are currently two main mutation routes:
Egg Spawn → Silver / Golden / Rainbow
Sakura Mutation Route:
Crane → Unlock Sakura Incubator → Sakura Crystals → Bloom / Spirit Bloom
How to Get Silver, Golden & Rainbow Mutations
Current guides consistently report that Silver, Golden and Rainbow can appear directly on egg spawns. Admin Abuse can also create opportunities to obtain mutated eggs.
| Mutation | Current Reported Multiplier | Main Acquisition Route | Exact Spawn Chance |
|---|---|---|---|
| Silver | 1.25x | Egg spawn / Admin Abuse | Not reliably confirmed |
| Golden | 2x | Egg spawn / Admin Abuse | Not reliably confirmed |
| Rainbow | 2.5x | Egg spawn / Admin Abuse | Not reliably confirmed |
How to Get Bloom & Spirit Bloom
Bloom and Spirit Bloom are tied to the Sakura Incubator. Unlike normal spawn mutations, these are applied to an egg through the Cherry Blossom progression system.
| Outcome | Current Reported Multiplier | Current Reported Chance | Source Route |
|---|---|---|---|
| Bloom | 1.5x | 97.5% | Sakura Incubator |
| Spirit Bloom | 3x | 2.5% | Sakura Incubator |
These percentages are current August 2026 guide/interface data and should be treated as update-sensitive. If the Incubator UI changes, LOLGA should update this table immediately.
How to Unlock the Sakura Incubator
The Mutation Guide should explain the route briefly, while the full unlock process belongs on the dedicated Crane page. Current update coverage reports that you need to obtain an Epic Crane from the Cherry Blossom Zone and submit it to the Sakura Incubator for the initial unlock.
1. Get Crane
Hatch the Epic Crane from Cherry Blossom Zone eggs.
2. Unlock Sakura Incubator
Bring Crane to the Incubator and complete the unlock interaction.
3. Farm Sakura Crystals
Participate in Great Bloom and collect the resource used by the Incubator.
4. Mutate Your Egg
Use the Incubator for a Bloom or Spirit Bloom result.

See the complete Crane unlock, Sakura Crystal and Great Bloom steps in the dedicated guide.
How Rare Is Spirit Bloom?
Current Sakura Incubator coverage commonly reports Spirit Bloom at 2.5% and Bloom at 97.5%. That makes Spirit Bloom the chase outcome from this system.
A 2.5% chance does not mean every 40th attempt is guaranteed. It describes the probability of an individual roll unless the live game explicitly shows a pity or guarantee mechanic.
Do Mutations Stack With Pet Size or Survive Fusion?
Current evidence supports that size/weight and mutation are separate pet properties. However, the exact formula for how every size tier and mutation combine should be tested before publishing a universal stacking equation.
Multiple current guides also report that mutated pets can be used in Fusion, but that the mutation may be lost when the fusion inputs do not all carry compatible mutations. Because Fusion outcomes can change with updates, use valuable mutated pets carefully until the live behavior is confirmed.
This section can be updated whenever a new controlled comparison, clearer Steal DNA screenshot or in-game UI change becomes available. That makes the page a living research reference instead of a static copy of one community table.
Steal an Egg Mutations FAQ
What are all the mutations in Steal an Egg?
Current August 2026 guides consistently list Silver, Golden, Rainbow, Bloom and Spirit Bloom.
What is the best mutation in Steal an Egg?
Current guide data places Spirit Bloom first at a reported 3x multiplier, followed by Rainbow at 2.5x. LOLGA's in-game test section is reserved to verify these values independently.
How do you get mutations in Steal an Egg?
Silver, Golden and Rainbow can appear on normal egg spawns or during Admin Abuse. Bloom and Spirit Bloom come from the Sakura Incubator.
What is the Spirit Bloom chance?
Current Sakura Incubator data commonly reports Spirit Bloom at 2.5% and Bloom at 97.5%. These rates can change after updates.
How do you get Rainbow mutation?
Rainbow is currently reported as a natural egg-spawn or Admin Abuse mutation. A reliable developer-confirmed exact spawn percentage has not been established in the sources reviewed.
Do mutations stack with pet size?
Mutation and size/weight are separate properties, but LOLGA should test the exact combined MPS formula before stating a universal stacking multiplier.
Can mutations survive Fusion?
Current guides report that mutations can survive Fusion, but the mutation may be lost depending on the input pets. Avoid risking a high-value mutation until the live fusion behavior is confirmed.
