The Great Bloom in Steal An Egg - Sakura Incubator and Bloom Mutations

The Great Bloom is the limited event that turned Steal An Egg mutations from a mystery into a system with published odds. Announced on screen as “The Great Bloom is live!”, it runs in a cherry-blossom area built around the Sakura Incubator, where you deposit Sakura Crystals to charge an egg and then mutate it — with the game itself printing the odds of each outcome. This guide walks through every screen we have verified letter by letter, explains what Bloom and Spirit Bloom actually do to your pets, and shows how to play the event without wasting crystals.

What The Great Bloom Is

During the event, a Sakura-themed zone opens with pink cherry-blossom trees and a large incubator structure at its center. The top banner reads “Sakura Incubator”, and a second line counts down the cycle: “Next Great Bloom in 25:13” — the event recurs, so missing one window is not a disaster. A crystal counter sits at the top of the interface; we observed it at 1.6K crystals ticking upward in +30 steps as the player collected in the zone.

The whole event is built around one idea that makes it unique in Steal An Egg: instead of hatching an egg and hoping its mutation roll went your way, you mutate the egg first, watch the outcome, and only then hatch it. It is the difference between buying a mystery box and cracking it open in the shop.

Getting In: The Crane Gate

The Sakura Incubator is not freely usable — two sessions we verified (August 2026) show the same unlock chain. The blossom area is guarded by a large kitsune, and the eggs it watches over can hatch a Crane. Take the Crane to the Dormant Sakura Tree and use the prompt — the screen reads “Hatch and Return Crane” — and the Cherry Blossom incubator unlocks. The Crane carries its own tag: “Epic / Crane / $4K/s”, verified by zoom crop. Budget for the detour: your first event loop is hatch a Crane, return it, and only then start charging eggs.

Verified: How Charging Works

The central panel reads “Charge Your Egg! Deposit Sakura Crystals to charge your egg!”, and every element on it was verified letter-exact across two independent frame reads (August 2026):

Element (exact screen text)	What it does
0% START → 100% CHARGE	The charge meter your Sakura Crystals fill
150% MAX CHARGE	The meter’s ceiling, well past the unlock point
“Place Egg — Choose an egg to mutate”	Opens the Select an Egg panel
“Mutate (Unlocks at 100%)”	The mutation button, locked until fully charged
“Possible Mutations: Bloom 97.5%, Spirit Bloom 2.5%”	The event’s published odds

The flow is simple. Open the panel with Place Egg, choose which of your eggs to load, dump Sakura Crystals until the meter passes 100%, and the Mutate button unlocks. The 150% MAX CHARGE marking suggests overcharging is possible — and the odds panel below is where it gets interesting.

The Odds Panel Moves: Three Verified Screens

The single most important thing we can tell you about The Great Bloom is that the published odds are not fixed. We have three letter-exact reads of the same Possible Mutations panel from three different gameplay sessions, and the numbers differ:

Panel state (all verified August 2026)	Bloom	Spirit Bloom
0% charged, Mutate still locked — three separate sessions	97.5%	2.5%
Fully Charged at the 150% MAX mark, egg ready to mutate	60%	40%
While a paid “Luck Boost 3” was active	90%	10%

Read the table honestly: three sessions quoting 97.5%/2.5% at rest makes that the event’s default quote, and the 60%/40% screen is one observation — but it is a letter-exact one, and it ties the odds shift to a fully charged egg. The game never explains the formula, so treat the panel as the only source of truth: read the odds on your own screen before you press Mutate, because they move.

The third row has a name. A purchase dialog read “Luck Boost 3” at 160 Robux, and the panel carried a green badge reading “2x Great Bloom Odds (2/3)” — a three-charge consumable that doubles the displayed Great Bloom odds. While it was active, the panel read Bloom 90% / Spirit Bloom 10%. That is a paid item changing published odds — worth knowing before anyone tells you the event is pure luck.

Bloom vs Spirit Bloom: The First Published Odds

This panel is the biggest deal in the event. “Possible Mutations” is the only place in Steal An Egg where mutation odds are printed on screen — everywhere else, rates are unverified guesses. Read it honestly, though. The numbers describe this event’s two known outcomes at the moment you screenshot them; they say nothing about the chance of a random hatch coming out Mutated outside the event. What they prove is that the game publishes rates when it wants to, which makes every unnamed “1 in X” quote on random fan sites even less trustworthy.

Spirit Bloom is the rare outcome, and it has now happened on camera twice: a result banner reading “Your Snowy Owl Egg is now Spirit Bloom!” — the first verified Spirit Bloom (August 2026) — and then “Your Eternal Lunar Dragon Egg is now Spirit Bloom!”, whose hatch tag read “Eternal / Spirit Bloom Eternal Lunar Dragon / $538M/s”. That is the first verified Spirit Bloom income, and it proves the mutation rides the pet tag as a prefix just like Bloom does. It is in our pet value list. Bloom is the common outcome, and its effect is measurable.

What “Your Egg is now Bloom!” Means

When the mutation resolves, the result banner reads “Your Eternal Lunar Dragon Egg is now Bloom!”. A second session produced the same format for a different species: “Your El Maja Egg is now Bloom!”. Two facts hide in those sentences. First, the mutation applies to the egg, not to a hatched pet — which is why the system can publish clean odds. Second, Bloom stacks on top of the label: an Eternal egg becomes an Eternal Bloom egg, exactly the stack the mutations guide describes as label plus mutation layer.

The income evidence for what Bloom does comes from the same month of gameplay. An overhead tag reading “Eternal / Bloom Mosasaurus / $238M/s” — verified twice — sat one server away from a plain “Eternal / Mosasaurus / $194M/s”. Same species, one Bloom layer apart: about 1.2× the income. That pairing comes from two different players with different multipliers, so treat 1.2× as one observed data point, not a fixed rate. The El Maja chain points the same direction: the egg that read “is now Bloom!” hatched into an El Maja ($4.4B/s) roster slot, while another player’s Silver El Maja (a size prefix on the same species) read $573M/s — but sizes and multipliers differ there, so we publish the two numbers without dividing them. It is all far gentler than the Rainbow premium (Rainbow La Vacca at 3× its base), which tells you the prefix hierarchy is real and worth learning. Bloom keeps pricing itself across players: a Bloom Oni Tiger tag read $723M/s on one player and $74B/s on an x4K-multiplier player’s top pet — same tag, different multipliers, which is why every Bloom number travels with its holder.

How to Prepare for the Next Bloom

No verified crystal farming rates are published, so the honest preparation is logistical, not numerical. The players who profit from the event are the ones who arrive with a plan; the screens we verified show the loop clearly enough to build one.

Step	Action	Why
1	Collect Sakura Crystals in the blossom zone during the event	The counter ticks up as you gather; no crystal income, no mutation
2	Decide your target egg before you charge	Crystals go into one egg — pick the label you actually want Bloomed
3	Charge past 100% and press Mutate	The button stays locked below full charge
4	Expect Bloom, hope for Spirit Bloom	97.5% versus 2.5% — the rare outcome is a bonus, not a plan
5	Hatch the Bloomed egg and compare incomes	The live income display is the only verified judge

Two honest warnings. Do not dump crystals into a filler egg because it was first in the panel — the mutation is permanent value attached to that egg. And the overcharge question now has one verified observation: the only fully charged egg we have screenshotted showed the panel at 60%/40% instead of the resting 97.5%/2.5%. That is one reading, not a formula — but it is reason to charge to the 150% MAX mark and check your own panel before pressing Mutate, rather than mutating at exactly 100%.

Since that event, the game’s second published odds table has arrived: the Monster Chest in the Monster Update pays a 1.5% Monstrous Egg — “Guaranteed Monstrous Mutation” — extending this same mutation family at much harsher odds than Spirit Bloom’s 2.5%.

FAQ

What is The Great Bloom in Steal An Egg? A recurring limited event in the Sakura Incubator zone where you deposit Sakura Crystals to charge an egg and then mutate it, with the game publishing the odds of each outcome on screen. How do you unlock the Sakura Incubator? Hatch a Crane from the kitsune-guarded eggs in the blossom zone, then use the “Hatch and Return Crane” prompt at the Dormant Sakura Tree — the incubator unlocks (verified in two sessions, August 2026).

What are the real Bloom mutation odds? They move. Three sessions quote Bloom 97.5% / Spirit Bloom 2.5% at 0% charge; a fully charged egg’s panel read 60% / 40%; with the paid “Luck Boost 3” (160 Robux, “2x Great Bloom Odds (2/3)”) active it read 90% / 10% (all August 2026). The panel is the only truth — read it before you mutate.

Does the Bloom mutation apply to the egg or the pet? To the egg. The result banners read “Your Eternal Lunar Dragon Egg is now Bloom!” and “Your El Maja Egg is now Bloom!” — you mutate first and hatch after, which is why clean odds can exist.

How much does a Bloom pet earn? The verified pairing: an Eternal Bloom Mosasaurus read $238M/s against a plain Eternal Mosasaurus at $194M/s — about 1.2×, observed across two different players (August 2026). A Bloomed El Maja read $4.4B/s against another player’s Silver El Maja at $573M/s, but sizes and multipliers differ there. Income varies with player multipliers, so treat every ratio as one data point.

What happens above 100% charge? One verified observation: the only fully charged (150% MAX) egg we screenshotted showed Spirit Bloom at 40% instead of the resting 2.5%. The game never explains the formula, so treat it as one data point — but charge past 100% and check your own panel before mutating.

When is the next Great Bloom? The event recurs — a banner read “Next Great Bloom in 25:13” during one cycle (August 2026). Check the Sakura Incubator banner in-game for the live countdown.
