Steal An Egg Alien Biome 2026: Nov 7, 11 AM ET, What's Known

Saturday, Nov 7 at 11 AM Eastern is when the Steal An Egg Alien Biome opens, by the developer's Roblox listing. That's 16:00 UTC and 8 AM Pacific. The teaser is pure story: a character called Paranoid Pete, a radar and UFO sightings. It names no egg, pet or reward, and the game's Robux store had no alien item when we looked.

Checked Nov 3 at 20:19 UTC from the developer's 12 Roblox event listings, its Robux product list and our hourly player tracker. Rolimons figures are marked.

What parents need to know:

• Roblox labels Steal An Egg Minimal, "Suitable for everyone".
• The game's own how-to says "Steal eggs from other players", so losing an egg is part of play.
• The Alien Biome listing mentions nothing paid. Four earlier themed updates each added a "Limited Egg" pack for Robux, from 99 Robux for one egg to 3,499 for fifty.
• Roblox's parental controls let you "set a monthly spending limit" on what your child spends on Roblox.

Key Takeaways

• The listing runs from 16:00 UTC on Nov 7 to 19:00 UTC on Nov 14.
• It is the developer's 12th Saturday listing in a row, and only the second with "biome" in its title.
• Paranoid Pete is new. None of the 11 earlier listings mentions him.
• On the last three update Saturdays, our launch-hour reads ran 5.4 to 6.7 times the same hour a day earlier.
• None of the game's 118 developer products (plus 2 older game passes) had an alien or UFO name at our read.

The 11 listings before this one all opened at 15:00 UTC. The later hour isn't a delay. NIST says daylight saving time in 2026 ran "to November 1 at 2 a.m.", so 11 AM Eastern now falls at 16:00 UTC. In the US, nothing changes. UK players get it at 4 PM, an hour later than the Oct 31 concert, which the developer billed at "3 PM GMT".

The end time is when Roblox stops showing the event as live. The developer hasn't said how long the biome itself stays. The listing's subtitle already reads "THE NEWEST BIOME IS HERE!", but its text says the biome "ARRIVES NEXT WEEK", so nothing is open before Nov 7.

What Happened: 12 Saturday listings since August

The developer is the verified Roblox group and Collect Rare Pets, 111,847,493 members at our Nov 3 read. It has posted one event listing for every Saturday since Aug 22. Nine ran for 24 to 28 hours. The Halloween Dimension ran a week, the concert ran an hour, and the Alien Biome is listed for 171 hours.

The two Halloween rows are covered in our Steal An Egg Halloween 2026 article.

The only earlier "biome" listing was the Enchanted Forest on Oct 3. Its text promised "A magical new biome", "New creatures to discover" and "Hidden secrets waiting to be found". That one was listed for 27 hours. The alien one is listed for a week.

The Alien listing went up at 16:29 UTC on Oct 31. That was 29 minutes after the concert listing closed, and the concert listing had told players to "Stick around for a BIG surprise!" The developer hasn't said whether the alien teaser was that surprise. The concert's badge, The Jonas Brother Concert, had 6,827,935 holders at our read.

One habit helps you plan. Each of the last seven listings was created on the Saturday before it went live. If that holds, the teaser for Nov 14 shows up on the game's Events list on Nov 7.

Why It Matters: the launch hour pulls 5 to 7 times the players

Chart: ObbyDesk. Source: Roblox player counts read by our tracker once an hour, last read 19:15 UTC Nov 3

Our tracker reads Roblox's player count for the game once an hour. Launch Saturdays look nothing like other days. At 15:06 UTC on Oct 17, six minutes into the Halloween Dimension, it read 10,055,373 players, 6.5 times the 1,546,431 of the same hour a day earlier. At 15:11 UTC on Oct 24 it read 9,488,617, or 6.7 times. Oct 31 is messier. The 15:00 read landed 12 seconds before the concert began, at 6,562,716 (5.4 times the day before). The next read, at 16:02 just after the concert ended, came in at 7,155,778 (6.5 times).

Desk note: Steal An Egg servers hold 7 players, by Roblox's game data. So 10,055,373 players meant at least 1,436,482 servers in that hour, even if every one was full. That's a lot of nests to rob.

Rolimons, a fan stats site, puts the all-time peak at 14,293,524 on Sept 19, the Saturday Sammy arrived (secondary).

The crowd between updates is shrinking, though. The busiest Tuesday hour fell from 1,517,109 on Oct 13 to 1,004,980 on Nov 3, down 34%. The Saturday highs in our reads fell 29%, from 10,055,373 on Oct 17 to 7,155,778 after the Oct 31 concert. Steal An Egg was still #1 on Roblox's Top Playing Now chart at 20:15 UTC on Nov 3, with 584,125 players. Our list of the most played Roblox games tracks that chart.

One spike has no listing behind it. The tracker read 3,760,397 at 15:18 UTC on Wednesday, Oct 28, and none of the developer's event listings covers that day. The full hourly history sits on our Steal An Egg game page.

For you, the takeaway is simple. If you want the first look, be in a server at 11 AM Eastern on Saturday. Spend that first hour finding out what the biome holds before you spend anything.

Will the Steal An Egg Alien Biome cost Robux?

The listing says nothing about Robux. At 20:19 UTC on Nov 3, none of the game's 118 developer products had an alien or UFO name, and neither did its 2 game passes, both from Aug 3. The newest product was created on Oct 31. That can change fast. Four earlier themed updates each got a Limited Egg pack 6 to 40 hours before launch.

Halloween also had gift versions at the same prices. Other launches brought other items. A Guardian Treadmill for 1,750 Robux appeared 16 hours before the Enchanted Forest. An [EXCLUSIVE] Burnin' Shell for 999 Robux appeared 8 hours before the concert. In all, 10 of the 11 earlier listings had at least one new Robux product created in the week before. The exception was Halloween Part 2.

Worth it? An alien Limited Egg pack, if one shows up: Wait. Every themed pack so far charged the same 3,499 Robux for 50 eggs, and nobody outside the developer knows what an alien egg hatches yet.

• If you're new: play the free route first and keep training Speed on the treadmill.
• If you're grinding: watch which alien pets other players hatch on day one before you buy eggs.
• For parents: Roblox's Minimal label applies. Anything sold for this update would be Robux, and a spending limit covers it.

Our take

Log in on Saturday at 11 AM Eastern; hold off on any alien egg pack until the eggs have names. The developer has listed an update for 12 Saturdays in a row, and launch hours have drawn 5.4 to 6.7 times a normal crowd. The teaser, though, is one paragraph of story with no item in it.

What we don't know yet: the names of the alien eggs and pets, how much Speed the biome needs, whether a paid pack comes, how long the biome stays after the listing ends on Nov 14, and what caused the Oct 28 spike.

Our view, from the sources in this article.

How we checked this

We read all 12 of the developer's event listings through Roblox's events API at 20:19 UTC on Nov 3. In the same minute we read the 118 developer products, 2 game passes, 8 badges, the game data and the group page. Player counts come from ObbyDesk's tracker, which has read the Roblox count every hour since Oct 11. Rolimons is a fan site and is marked. Time zones come from NIST and the developer's own concert listing. We don't play the game for articles, so nothing here describes the biome from inside.

Frequently Asked Questions

Are there Steal An Egg codes for the Alien Biome?

No. The game description, the developer's group page and all 12 event listings had no code at our Nov 3 read. The group has an empty description and no shout. Codes we can't find on the developer's own pages don't go on ObbyDesk. Our guide to Roblox scams covers fake code offers.
