Two days into Update 12, I’ve stopped caring about the eggs on the Alien Planet floor. The fishing loop is where the progress is. It pays out on a schedule, it doesn’t need Robux, and it’s the only place the new Divine actually comes from.

Here’s how it works, what’s confirmed, and where I think your time is best spent.

Quick facts

Fact	Detail
Where	Alien biome, past the Enchanted Forest (250B Speed on the egg sign)
Starter rod	Alien Rod, free from the Alien Ferryman
Lagoon unlock	Catch 20 fish, then talk to the Ferryman again
Currency	Void Pearls, earned from fishing and milestones
Dark Matter Mutation	1,750 Void Pearls, 30% chance, x2.5 income
Cosmic Eclipse	Every 30 minutes, at :25 and :55
Nebuloth Kraken cap	750 per round, shared across all servers
Update 12 listing	Runs until Sat 14 Nov: 11am PT / 2pm ET / 7pm GMT / 6am AEDT (Sun 15 Nov) / 8am NZDT (Sun 15 Nov)

How to start fishing

You don’t need to buy anything. You do need to be inside the Alien biome, so if you’re still under the Speed sign, train first. My Speed guide has the quickest routes.

1. Find the Alien Ferryman. He stands by the water in the Alien biome.
2. Take the Alien Rod. Equip it and cast into the nearby water.
3. Catch 20 fish. This is the gate for the Lagoon.
4. Talk to the Ferryman again. He takes you across to the Alien Lagoon by boat.
5. Stay there. Night doesn't reset you in the Lagoon, so you can fish through it.

That last point is bigger than it sounds. Anywhere else in Steal An Egg, nightfall is a timer you play around. In the Lagoon it’s just a different sky, which makes this the comfiest grind the game has ever had.

Fishing Milestones and the rods

Every fish you land adds one point to Fishing Milestones. The update announcement describes 100 milestone stages, with rods, Void Pearls, eggs and Dark Matter Mutations along the way. Open the Milestones menu in game to see your next reward, because that screen is the real source of truth.

The four upgrade rods are the Xeno, Lunar, Void and Kraken Rods. Creators and guides are reporting these unlock points:

Rod	Fish caught (reported)	What it's for
Alien Rod	Start	Unlocking the Lagoon
Xeno Rod	100	First Void Pearl boost
Lunar Rod	750	Bigger Pearl boost
Void Rod	2,250	Late-game Pearl farming
Kraken Rod	5,000	Best rod, comes with an Abyssjaw Egg

I’m only listing fish counts that more than one source agrees on. A few guides also print exact Pearl multipliers per rod. I haven’t seen those on an official screen yet, so I’m leaving them out rather than guessing.

Void Pearls and Dark Matter

Void Pearls are the currency of the whole fishing loop. You earn them from catches and milestone rewards, and better rods earn more per catch.

The thing you spend them on is the new Dark Matter Mutation. At the Alien Trade-In (talk to the Ferryman), 1,750 Void Pearls buys one Dark Matter consumable. You use it on a placed egg, and it has a 30% chance to apply a x2.5 income mutation.

Thirty percent sounds decent until you do the math. On average you’ll need a bit over three tries per success, which is around 5,800 Void Pearls for one Dark Matter egg.

• Use it on: your best egg, the one you'd hatch into your top earner.
• Don't use it on: a random egg you're about to get stolen from your base.
• Remember: a miss is gone. There's no refund screen.

The Cosmic Eclipse and the Nebuloth Kraken

This is the headline. The Update 12 notes say a Divine Nebuloth Kraken can be caught in the Alien Lagoon every 30 minutes, with 750 catches per round shared across the whole game. An on-screen counter tracks it, and when it fills, the round is over.

Players have clocked the Cosmic Eclipse starting at 25 and 55 minutes past every hour. Because all five of my usual time zones (PT, ET, GMT, AEDT and NZDT) sit on whole-hour offsets, it’s the same minute mark wherever you live.

Do this	Why
Be in the Lagoon a minute early	The counter is global, so late arrivals lose
Use your best rod	Faster catches mean more attempts per round
Don't hop servers mid-round	Loading screens eat the window
Ignore "auto catch" scripts	Exploits break Roblox rules and can get you banned

Relics and the secret fusion room

While fishing, you can also pull up colored Relics. There are seven colors (red, orange, yellow, green, blue, purple and pink), and collecting all seven opens a locked door in the Alien biome. Players report Relics turn up more often in the Lagoon than in open water.

Behind the door is a fusion machine that uses two Divines, the Obsidian Rex and the Nebuloth Kraken. Creators are showing a new pet called the Xenorath coming out of it. The exact fusion math floating around is community-shared, so I’m not printing numbers until the game shows them plainly.

The Crystal Egg (what I’d skip)

Update 12 also added a limited Crystal Egg to the Shop’s Featured tab, bought with Robux only. It’s reported to stay until around 21 November. The shop screen lists six pets with these chances:

Rarity	Chance per egg
Legendary	39%
Mythic	24%
Cosmic	18%
Secret	12%
Eternal	6.5%
Divine	0.5%

Prices are 99 Robux for one, 249 for three, 799 for ten and 3,499 for fifty. At 0.5%, you’d need about 200 eggs on average to see the Divine. Even at the best pack price, that’s four 50-packs, or roughly 14,000 Robux. Some players will hit it on egg three. Most won’t.

What I’d do this week

1. Unlock the Lagoon tonight. Twenty fish is fast.
2. Push to the Xeno Rod. A hundred fish is a fair first target.
3. Plan around :25 and :55. Two Kraken rounds an hour, every hour.
4. Save Pearls for one smart Dark Matter try. Best egg only.
5. Keep the Robux. Free routes are better value this update.

If you want the bigger picture on Update 12 (the ship raid, the Speed gate, the Tidal Surge), my Alien Biome Update 12 guide has it, and my day-one scorecard covers whether the whole thing is worth your weekend. For visuals, YamashiP, RFG and ViewSIM are all solid, and the rest of my list is on YouTubers I follow.
