You can grab the Huge Cosmic Egg in Steal An Egg even at low speed by running two accounts: use an alt to bait the Cosmic Boss into the wall by the Sakura Incubator so it ragdolls, then switch to your main, snatch the Huge Egg from the nest, and sprint it back to the Safe Zone while the boss is stuck.
The Huge Cosmic Egg sits in the game’s final zone, guarded by the fastest boss in Steal An Egg, and the signpost by the nest asks for a punishing 700M speed to outrun it. Most players nowhere near that number assume the egg is locked away, but there’s a glitch that lets you take it with a fraction of the recommended speed, plus a slower legit route if you’d rather earn the number honestly. Below covers both.

What the Huge Cosmic Egg is in the Cosmic biome
The Cosmic biome is the end-game area, set in a cherry-blossom zone with the Sakura Incubator at its far end. Its egg nest sits under a Recommended signpost that posts 700M speed, because the guardian here — the Cosmic Boss, a Dragon-type — is the fastest guardian in the game and will run you down if you’re too slow.
“Huge Cosmic Egg” is how the community refers to a Cosmic-zone egg that rolls the Huge size — it isn’t a separate, formally named item. Size in this game is shown as a weight, and a Huge roll is both taller than your character and worth many times the income of a normal one, which is exactly why it’s the zone people grind toward. This guide covers the two ways in: a low-speed glitch using a second account, and the legit speed grind if you’d rather do it clean.
How to steal the Huge Cosmic Egg with an alt account in Steal An Egg
Key The trick is that the Cosmic Boss can be parked out of the fight entirely, so your main never has to outrun it.
How to steal the Huge Cosmic Egg with the two-account boss trick in Steal An Egg
You’ll use the alt to strand the Cosmic Boss against a wall, then walk your main in to take the Huge Egg while it’s helpless.
STEP 1/7
Open two accounts at once
Log into your main and an alt in separate Roblox windows so both stand at the Cosmic nest.
STEP 2/7
Send the alt up with a small egg
Grab a small egg on the alt and run it upward along the course to pull the Cosmic Boss into chasing you.
STEP 3/7
Reach the far end of the zone
Keep the alt running all the way to the end of the course by the Sakura Incubator, boss in tow.
STEP 4/7
Bait the boss into the wall
Lead the Cosmic Boss straight into the wall by the Sakura Incubator so it crashes and ragdolls, taking it out of the chase.
STEP 5/7
Switch to your main and grab the Huge Egg
With the boss stuck, hop to your main account, walk to the nest, and snatch the Huge Egg.
STEP 6/7
Run the egg back through the course
Carry it back through the obstacle course, threading the lava pits, bones and water hazards while the boss is still down.
STEP 7/7
Cross into the Safe Zone
Reach the SAFE ZONE at the start of the map to trigger the “You stole an EGG!” payout and lock in the egg.

Reaching 700M speed the legit way
| Biome | Recommended speed |
|---|---|
| Forest | None |
| Lake | 900 |
| Desert | 10K |
| Jungle | 40K |
| Snow | 170K |
| Volcano | 700K |
| Abyss Ocean | 2.5M |
| Prehistoric | 17M |
| Cosmic | 700M |
If you’d rather not juggle two accounts, you have to actually hit the number — and the number is big. Speed comes from three places that stack: grind the Treadmill in front of your base and keep upgrading it with pet income, buy the strongest Trail you can afford (Trails act as a flat speed multiplier), and use Robux Speed packs — which run from +150K all the way up to +1B — or a limited-time event when one is live for a big jump.
The important part is not to aim for exactly 700M. A Huge egg is heavy, and its weight drags your speed down while you’re carrying it, so a player who only just meets the minimum gets caught the moment they pick the egg up. Overshoot the Cosmic requirement comfortably so you still have margin under load. For context, here’s what every biome asks for, so the Cosmic jump lands:
Before you grind anything, like and favorite the game and join its Roblox community for a free +10,000 speed — an easy early leg-up that clears the first couple of biomes outright.
Pets the Cosmic Egg can hatch
| Pet | Rarity | Income/sec |
|---|---|---|
| Cosmic Gorilla | Mythic | $180k/s |
| La Vacca Saturno Saturnita | Cosmic | $2.2m/s |
| Cosmic Skeleton Boss | Secret | $45m/s |
| Cosmic Dragon | Secret | $60m/s |
The reason the Cosmic Egg is the end-game target is what comes out of it. The zone’s index runs from strong to absurd, and a Huge roll multiplies the income on top of that. The premier chase pet is the Unicorn (Divine), which reaches roughly $1B/sec in a built-out setup — a single good Cosmic hatch can reset your whole economy.
Mistakes that get you caught, and fake codes to ignore
The most common failure is undershooting speed. Players walk in at or just under 700M, pick up a Huge egg, and get run down because the egg’s weight drops them below the Dragon guardian’s pace — the fastest in the game. Give yourself real headroom above the posted number so the weight penalty doesn’t sink you.
The second mistake is treating Cosmic like an earlier zone. Routes that worked in Jungle or Prehistoric don’t account for a faster guardian and a heavier egg, so pre-plan a clean, straight escape line to the Safe Zone instead of improvising. And ignore any “Huge Cosmic Egg code” lists — there is no working redeem code and no in-game code UI, so those are fabricated. Your real free boost is the like/favorite/join freebie above.

Frequently Asked Questions
Can another player grab the Huge Egg while I’m carrying it back?
Yes. While you’re running an egg from the nest to your base, another player can smack you and knock it loose, and then it’s theirs to pick up. The egg is only truly safe once it’s sitting in your personal pen — until it crosses into your base, it can be taken off you mid-carry.
Does the Cosmic Egg hatch on its own after I secure it?
No. When the timer runs out the egg does not open itself. You have to go back to your farm and press the hatch button for the pet to actually reveal — leaving it alone won’t do anything.
