Bloom and Spirit Bloom only come from the Sakura Incubator in Steal an Egg. The machine sits at the back of the Cherry Blossom Zone, the last biome on the map, and it will not run until you hand it a Crane and enough Sakura Crystals to finish a charge.
Quick answer: Put an unhatched inventory egg into the unlocked Sakura Incubator, charge it to at least 100 percent with Sakura Crystals, then click Mutate. Bloom lands 97.5 percent of the time. Spirit Bloom lands 2.5 percent of the time.
Bloom and Spirit Bloom mutation chances
The incubator rolls one of two mutations. There is no special egg and no extra item for Spirit Bloom. Every valid egg that reaches a full charge uses the same roll.
| Mutation | Multiplier | Chance |
|---|---|---|
| Bloom | 1.5x | 97.5% |
| Spirit Bloom | 3x | 2.5% |
Spirit Bloom is simply the rare side of that roll. You may need several charged eggs before it appears. Robux can raise Spirit Bloom luck if you do not want to wait on the 2.5 percent rate.
Charge percent required to mutate
Sakura Crystals are the only fuel. Deposit them after the egg is in the machine. The egg does not mutate until charge reaches 100 percent.
| Charge | What happens |
|---|---|
| Below 100% | Mutate will not finish a Bloom or Spirit Bloom roll. |
| 100% | The egg can be mutated. Bloom is 97.5%. Spirit Bloom is 2.5%. |
| 150% (max) | Charge cap. Improves the Spirit Bloom roll. Does not lock the rare result. |
Push the bar to 150 percent when you are hunting Spirit Bloom. A max charge still uses the same two outcomes. It only makes the rare side more likely.
Eggs the Sakura Incubator will not accept
The machine only takes an egg that is still in your inventory. A hatched pet cannot go in. An egg already laid down in your pen cannot go in either.
If you want Bloom or Spirit Bloom on a rare pet, keep that egg unhatched until after Mutate finishes. Once it hatches or hits the pen, the incubator is closed to it.
Use the Sakura Incubator
If Mutate does nothing, the usual blockers are a charge under 100 percent, a hatched pet, or an egg that is already in your pen. Fix that input and run the charge again.
Unlock the Sakura Incubator
The incubator stays sealed until you offer a Crane. Crane is an Epic pet from Cherry Blossom Zone eggs. You only need to do this once.
| Requirement | Detail |
|---|---|
| Location | Back of the Cherry Blossom Zone |
| Unlock pet | Crane (Epic) |
| Speed to steal those eggs | At least 3.5B |
| After you submit Crane | The pet is consumed. The machine stays unlocked. |
You know the unlock worked when the machine accepts eggs and Sakura Crystals. A Great Bloom timer also appears above it. If you still want a Crane in your collection, hatch a second copy before you spend the first one.
Sakura Crystals and the Great Bloom Event
Unlocking the incubator also opens the Great Bloom Event in the Cherry Blossom Zone. Sakura Crystals drop only during that window, from Crystal Cherry Blossom Trees.
| Event | Repeat | Length | How crystals drop |
|---|---|---|---|
| Great Bloom Event | Every 30 minutes | About 3 minutes | Hit Crystal Cherry Blossom Trees with your baseball bat |
An on-screen message appears when Great Bloom starts. After the incubator is unlocked, the timer above the machine also shows the next run. Be in the Cherry Blossom Zone before that message appears. The three-minute window is too short to spend on travel from another biome.
Equip the baseball bat as soon as the event starts and smash the crystal trees until the timer ends. Bank those Sakura Crystals for the next 100 percent or 150 percent charge. After the first Crane, this crystal loop is the only resource grind the incubator still asks for.
