Steal An Egg Item Atlas and strategy guide

A practical encyclopedia for the items and systems players keep checking: eggs, pets, treadmill, Trails, base upgrades, mutations, incubator content, and event items.

Encyclopedia

Items and systems players should understand first

The official listing confirms the main loop. Community guides add update-sensitive details such as biome thresholds, Trail tiers, and mutation multipliers. Each item below keeps that split visible.

Core item

Eggs

Evidence: Official gameplay confirms stealing eggs and hatching pets.
Use: Eggs are the run target. Pick eggs from a biome your Speed can clear with a buffer.
Guide: Measure a full out-and-back route. If guardians catch you often, train Speed or buy a practical Trail before targeting heavier eggs.

Income item

Pets

Evidence: Official gameplay confirms pets generate money; player guides track income by biome.
Use: Pets fund base upgrades, treadmill upgrades, and future Speed progress.
Guide: Compare the income shown in your own game, then use the income calculator instead of trusting stale screenshots.

Progression upgrade

Treadmill

Evidence: Official gameplay confirms treadmill upgrades and Speed training.
Use: The treadmill raises Speed, which supports later biome runs.
Guide: Measure your Speed gain for one minute, save it in the calculator, and train toward the next biome plus a safety buffer.

Speed multiplier

Trails

Evidence: Community guides report trails as Speed multipliers with tiered costs.
Use: Trails multiply your effective Speed and can make a biome route safer.
Guide: Do not buy the most expensive trail you can barely afford. Compare the multiplier gain against how long it delays pet or treadmill upgrades.

Storage upgrade

Base

Evidence: Official gameplay confirms base upgrades.
Use: A stronger base supports more progression value from your pet income.
Guide: Upgrade base capacity when good pets are waiting or when income is capped by storage rather than Speed.

Income multiplier

Mutations

Evidence: Community guides report Silver, Bloom, Golden, Rainbow, and Spirit Bloom multipliers.
Use: Mutations multiply pet income and can change which pet is worth keeping.
Guide: Use the mutation calculator with your visible pet income. Do not rely on unknown hatch odds unless you measured them yourself.

Event mechanic

Sakura Incubator

Evidence: Community guides report Bloom and Spirit Bloom outcomes.
Use: Reported as a path for Bloom-style mutations during Sakura content.
Guide: Only plan around the incubator when it is visible in your current update. Mark removed or rotated mechanics as unknown.

Live event

Monster Update

Evidence: Official Roblox event page exists; detailed rewards are unconfirmed here.
Use: Event hub for timing and official launch link.
Guide: Use the event page for attendance. Do not assume new pets, codes, odds, or rewards before live evidence exists.

Biome reference

Speed, guardians and route planning

These thresholds are community reported and should be rechecked after updates. The tools page adds a safety buffer rather than assuming the listed minimum is enough for every egg.

Biome	Speed	Guardian	Guide
Forest	Start	Chicken	Use this area to fill early Index slots and fund the first treadmill and trail upgrades.
Lake	900	Swan	Treat the listed speed as the entry point. Add a buffer before carrying heavier eggs.
Desert	10K	Scorpion	A sharp first jump. Farm stronger early pets before pushing every run here.
Jungle	40K	Tiger	Good target once early income is stable. Do not ignore trail multipliers.
Snow	170K	Yeti	Bring a safety buffer. Reported sources warn minimum speed is not always enough.
Volcano	700K	Hellhound	Useful breakpoint for higher-income pets, but failed carries waste long travel time.
Abyss Ocean	2.5M	Moby	Start comparing time per run against income per hatch before committing long sessions.
Prehistoric	18M	T-Rex	A large progression jump. Use income planning before chasing rare eggs here.
Cosmic	700M	Dragon	Minimum speed is only a baseline. Larger eggs need a personal safety margin.
Cherry Blossom	2.5B	Nine-tailed fox	Newest high-end target in community reports. Recheck after every Saturday update.

Multiplier systems

Trails and mutations are planning items

Trails affect Speed planning, while mutations affect income planning. Both are better handled with calculators than with a static best-item claim.
