The Update 8 patch notes for Steal an Egg end with a teaser: a two-part Halloween event and a new dimension for the following week. The game's official Roblox event lists Halloween Dimension for Saturday, October 17, 2026. That is all the official side has said so far. This guide separates what is confirmed from what is not, then shows how to get ready using pets, bosses and systems that already exist in the game today.
What is confirmed about the Halloween Dimension
The wiki has no page for the Halloween event yet, so the facts below come from the Update 8 patch notes and the game's official Roblox event listing, which we read as quoted by our own update log.
| Fact | Status |
|---|---|
| A two-part Halloween event is coming | Confirmed in the Update 8 notes |
| A new dimension arrives the week after Update 8 | Confirmed in the Update 8 notes |
| The event is called "Halloween Dimension" | Confirmed on the official Roblox event listing |
| Date: Saturday, October 17, 2026 | Confirmed on the official Roblox event listing |
| A gateway structure, bosses and secret eggs | Listed on the official event |
| Which pets, mutations or currencies it adds | Not announced |
| Speed requirement | Not announced |
| What "part 2" is and when it starts | Not announced |
We will not invent the missing rows. When the patch notes and the wiki have them, they will go into the update log.
Why "Halloween" here is not the same as the Angels & Demons zone
Players sometimes mix up spooky pets with the event. The darkness pets, skeletal pets and bosses that are in the game right now were added in earlier updates (Update 4 for the Demon side, Update 6 for the Skeletal pets). They are not Halloween event rewards. The table below is a list of spooky-looking pets you can already work toward, which will not be wasted whatever the event adds.
Spooky pets you can get right now
| Pet | Rarity | Base income | Where it comes from |
|---|---|---|---|
| Skeletal Sabertooth | Divine | $9B/s | Skeletal Egg |
| Skeletal Gigantus | Eternal | $4B/s | Skeletal Egg |
| Skeletal Dunkleosteus | Eternal | $2.5B/s | Skeletal Egg |
| Skeletal Giant Sloth | Secret | $900M/s | Skeletal Egg |
| Skeletal Terrorbird | Secret | $750M/s | Skeletal Egg |
| Skeletal Glyptodon | Secret | $550M/s | Skeletal Egg |
| World Burner | Divine | $5B/s | Angels & Demons (Darkness night) |
| Skeleton Horse | Eternal | $1.3B/s | Angels & Demons (Darkness night) |
| Gargoyle | Secret | $225M/s | Angels & Demons (Darkness night) |
| RazorFang | Secret | $350M/s | Angels & Demons (Darkness night) |
| Demon Hound | Cosmic | $25M/s | Angels & Demons (Darkness night) |
| Imp | Cosmic | $16M/s | Angels & Demons (Darkness night) |
| Wendigo | Secret | $15M/s | Rift |
| Eye Bat #021 | Legendary | $115K/s | Boss Mastery |
| Cosmic Skeleton Boss | Secret | $45M/s | Cosmic biome |
The strongest by income is Skeletal Sabertooth, a Divine at $9B/s from the Skeletal Egg. The Skeletal Egg comes from the Extinction Egg, a paid egg: Update 6 says the Extinction Egg has a small chance to reroll your hatch into a rare Skeletal version of the animal. For the full list, see the special eggs guide.
If you prefer a free route, the Darkness side of Angels & Demons gives World Burner at $5B/s and Skeleton Horse at $1.3B/s. Those need 20B Speed and a Demon night. See the Angels & Demons guide.
Practice the boss fights
The notes say the dimension has bosses. We do not know how they work, but the game already has two boss events that repeat every 30 minutes:
| Boss event | What you earn | Where to read more |
|---|---|---|
| Rift Boss | Boss Tokens, Boss Mastery points | Rift Event |
| Dr. Scramble (Mecha) | Samples, Boss Mastery points, tier progress | Dr. Scramble guide |
These events are a good way to get used to fighting while you wait. They also give points toward real rewards: Eye Bat #021 needs 10 Boss Mastery points and Pink Dragon Experiment #010 needs 100. We say "practice" because we do not know if the dimension bosses play the same way.
Keep your Shooting Stars and your Speed ready
Update 8 introduced mounts. The notes say the nightly Shooting Star event gives each eligible player a star, and that Stellaris sells up to 5 per week, with the limit resetting every Saturday. October 17 is also a Saturday, so that reset lands on the same day as the dimension. We do not know if the two are connected. Read the Mounts guide before you spend a star, because turning a pet into a mount cannot be undone.
For Speed, the dimension's requirement is unknown, so the safe plan is to keep climbing. Our speed guide shows every treadmill and trail step.
A checklist for before October 17
- 1Read the notes. When the patch notes are out, check them first. Our update log will carry the details.
- 2Free a pen slot. New pets need room. The base upgrade from Update 4 lets you equip one more.
- 3Do not spend a Shooting Star on a pet you may replace. Mounts are permanent.
- 4Do a few boss fights to learn the controls.
- 5Keep some cash. Secret eggs and shops usually want money, and we do not know the prices yet.
- 6Check mutations. Know which consumables you have. The mutations guide shows what each one does.
Do not fall for fake Halloween codes
Because the game has an event, fake sites will say "free Halloween egg" or "secret code". Steal an Egg has no redeem box, as our free rewards guide explains. If a site or video asks for your password, a Robux payment or a download, close it. A real reward comes from inside the game.
How we will update this page
When the Halloween Dimension launches, the wiki will get a page, and our data will fill in the pets, rewards, bosses and secret eggs. Until then, anything beyond the table at the top is a guess, and we leave it out.
