Steal An Egg game thumbnail — Steal an egg, outrun its guardian, then grow and hatch pets in your base.

#Steal An Egg — Documentation

#About this guide

Owner and maintainer documentation for Steal An Egg (Studio place Ukradnij jajko., place ID 114574417170451). Every number below was read from the place itself — ReplicatedStorage.SharedConfig and the services in ServerScriptService.Services — so it describes this build rather than an older design document.

#Start here

Setup & Configuration — read this before the first edit.
Stealing & Carrying and Guardians & Chases — the loop players repeat every session.
Growing & Hatching and Pets, Sizes & Mutations — where the reward comes from.
Troubleshooting — the failure shapes seen most often.

Each topic has its own page and is reachable from the sidebar.

#The core loop

Travel into a biome; the world holds several nests and one sleeping guardian.
Hold E on a nest prompt for one second to steal an egg.
The guardian on that biome wakes and chases you across the whole biome.
Reach Workspace.Spawn.SafeZone without being caught; the egg is delivered automatically.
The egg grows in your base — in a slot, or anywhere in the region when free placement is on.
Hatch it with E, roll size and mutation, and register the pet in the Index.
Place pets in your pen: only placed pets earn cash.
Spend cash on treadmills, trails, pen levels and fusion; spend Robux on boosts.

#Version notes

Config.VERSION is 1, Config.PROFILE_SCHEMA_VERSION is 2 and the DataStore is SAE_Profiles_v1.
Config.Flags.Rift is off: the Rift arena, its banners and its pets are built but not reachable in normal play.
Every Config.Monetization game pass and developer product still has id = 0, so MonetizationService.isConfigured() reports false and Robux purchases do nothing until those IDs are filled in.
Config.WikiSource records community wiki data fetched on 2026-09-12; WikiPets overrides grow times and income for the pets it lists.

Documentation reviewed against the place as opened in Studio. Re-check the module before you change a value — the tables here are a snapshot, not a live feed.
