Community mutation claims compared
This table records what current third-party guides claim; it is not an official multiplier table. Agreement can prioritize a test, but only readable game UI or a controlled before-and-after comparison can move a value into the verified column.
| Mutation name | Community claim | Current evidence status |
|---|---|---|
| Golden | 2× in AllThings.How and Beebom | Community agreement; no controlled in-game test retained |
| Silver | 1.25× in the same two guides | Community agreement; readable label and comparison still needed |
| Rainbow | 2.5× in two guides; another fan wiki claims 5× | Conflicting — do not publish either number as fact |
| Bloom | 1.5× in two community guides | Community agreement; not verified by this wiki |
| Spirit Bloom | 3× in two community guides | Community agreement; not verified by this wiki |
Source quality: secondary community guides. None of the compared pages is the Roblox creator or an official Steal An Egg patch note.
Rainbow mutation evidence snapshot
| Field | Observed value | Evidence status |
|---|---|---|
| Visible outcome | Rainbow Mosasaurus | Community video lead |
| Visible rarity | Eternal | Supported separately by an official Eternal hatch badge |
| Displayed income | $1.3B/s | Visible value; not a multiplier |
| Individual egg name | Unknown | “Rainbow Eternal Egg” may be descriptive video wording |
| Price and location | Unknown | Needs readable in-game UI |
The video is a discovery source, not first-party documentation. The wiki keeps the visible facts and unknown fields separate.
Readable in-game mutation field
The BIG Mosasaurus Steal DNA panel includes a visible MUTATIONS field and a gray icon. This proves that a captured result can expose a mutation slot in the result UI. The icon is not accompanied by a readable type name, so this wiki does not label it Stone, Rock, Gray or any other guessed mutation.
| Observed field | Visible value | Evidence limit |
|---|---|---|
| Result | BIG Mosasaurus · Eternal | Readable DNA panel |
| Displayed income | $5B/s | One 6,898,039kg instance, not a base value |
| Mutation field | Gray icon visible | Type name and multiplier are not shown |
What the official material supports
- The game description explicitly says players can discover mutations.
- Mutations are listed alongside eggs, pets and sizes, suggesting a separate attribute.
- An official thumbnail shows a rainbow-gradient egg with a snowflake symbol and altered text.
What the artwork does not prove
A snowflake icon may indicate an ice-themed variant, and the rainbow shell may indicate another property—but a promotional image is not enough to name the mutation, define the effect or assign a multiplier. We preserve the visual as evidence and leave the mechanics open.
Fields waiting for testing
| Field | Status | Evidence needed |
|---|---|---|
| Mutation names | Unknown | Displayed in-game label |
| Income multiplier | Unknown | Same base pet before/after comparison |
| Egg compatibility | Unknown | Repeatable hatch or egg UI evidence |
| Visual effects | Partially visible | Uncropped gameplay capture |
| Interaction with size | Unknown | Record showing both attributes |
How to verify a mutation multiplier
- Record the unmutated pet’s exact displayed income, rarity and size.
- Record the mutated version of the same base pet with upgrades and server state unchanged.
- Divide mutated income by base income and keep both screenshots with the patch date.
- Repeat the comparison on a second pet before treating the ratio as a general multiplier.
Use the income calculator to compare the two displayed values without turning one community observation into a universal rule.
Do not borrow mutation lists
Mutation names from other Roblox collection games are not automatically valid here. We will not publish a familiar-sounding list simply because another game uses Golden, Rainbow, Ice or similar labels.
