1. How to Enter the Alien Biome and Get New Pets
Alien Biome Unlock Requirement
The Alien Biome is a new area introduced in Update 12, located behind the Enchanted Forest.
- Required Speed: 250B Speed.
- Opening Time: November 7, 2026, at 16:15 UTC.
- Pet Rarities: The area features pets of different rarities, including Secret, Eternal, and Divine.
New Pets in the Alien Biome
The regular Alien Biome features several new pets:
| Pet | Rarity |
|---|---|
| Bloomfin | Legendary |
| Vexlet | Mythic |
| Bloomspire | Mythic |
| Glacigon | Cosmic |
| Redmaw | Cosmic |
| Aurora Stag | Secret |
| Viridian Prowler | Eternal |
| Obsidian Rex | Divine |
Obsidian Rex is one of the new Divine pets and is also involved in the hidden fusion system.
Besides the regular Alien Biome, players can also encounter a special event called Alien Tidal Surge.
Alien Tidal Surge
Alien Tidal Surge is a special weather event in the Alien Biome.
- It has a chance to occur during each in-game night.
- When it starts, the Alien Biome becomes flooded.
- The flooded map creates an underwater area where players can find exclusive pets and eggs.
The event features five exclusive pets:
| Pet | Rarity |
|---|---|
| Jellynova | Cosmic |
| Flarefish | Cosmic |
| Tideler | Secret |
| Abyssjaw | Eternal |
| Prismare | Divine |
Crystal Egg: New Limited Robux Egg
Update 12 also introduces the Crystal Egg, a limited-time egg available in the Featured section of the in-game Shop. Unlike the fishing rewards and Alien Biome pets, this egg requires Robux to purchase.
The Crystal Egg contains 6 pets with different rarity levels, including a Divine pet with a 0.5% drop chance.
Crystal Egg Pet Drop Rates
| Pet Rarity | Drop Chance |
|---|---|
| Legendary | 39% |
| Mythic | 24% |
| Cosmic | 18% |
| Secret | 12% |
| Eternal | 6.5% |
| Divine | 0.5% |
The Divine pet is the rarest reward, with only a 0.5% chance per egg. The Crystal Egg is expected to remain available in the Shop until around November 21, 2026, so check the in-game Shop before purchasing.
2. How to Unlock Fishing and Alien Lagoon
Fishing is one of the main features introduced in the Alien Biome. By fishing, players can progress through Fishing Milestones and unlock better rods, pets, and other rewards.
Get the Alien Rod
First, find the Alien Ferryman near the water in the Alien Biome.
Interact with the NPC to receive your starting fishing rod, the Alien Rod. Equip it and head to the nearby water to start fishing.
Unlock Alien Lagoon
The Alien Ferryman asks you to catch 20 fish to unlock Alien Lagoon.
Once you complete this requirement, talk to the NPC again. He will take you to Alien Lagoon by boat.
Alien Lagoon is a separate fishing area where you can continue catching fish, collecting Void Pearls, and progressing through Fishing Milestones. You can also keep fishing here without being sent back to the spawn area when night falls.
Another important advantage is that Relics are easier to obtain in Alien Lagoon than in the regular Alien Biome. If you are trying to collect all seven Relics, this is the better place to fish.
6. How to Unlock the Secret Fusion Area
Every successfully caught fish adds 1 point to your Fishing Milestones progress. As you catch more fish, you can unlock better fishing rods, Void Pearls, pets, and Mutations.
All Fishing Rods
Here are the currently known fishing rods and their Void Pearl bonuses:
| Fishing Rod | Fish Caught | Void Pearl Bonus |
|---|---|---|
| Alien Rod | Starting Rod | Not confirmed |
| Xeno Rod | 100 | ×1.15 |
| Lunar Rod | 750 | ×1.32 |
| Void Rod | 2,250 | ×1.52 |
| Kraken Rod | 5,000 | ×1.75 |
These rods can be unlocked through Fishing Milestones and do not need to be purchased separately. The Kraken Rod is currently the best known alien fishing rod, increasing your Void Pearl earnings by 1.75x.
Important Fishing Milestone Rewards
Fishing Milestones also provide pets, Void Pearls, and Dark Matter Mutation rewards.
| Fish Caught | Reward |
|---|---|
| 1,500 | Jellynova |
| 3,000 | 10,000 Void Pearls |
| 4,000 | Aurora Stag |
| 5,000 | Abyssjaw Egg |
The official update announcement confirms that the Fishing Milestones system has 100 stages. You can open the Fishing Milestones interface to check your current progress and see which reward comes next.
4. How to Get Void Pearls and Dark Matter Mutation
Void Pearls are an important currency in the Alien Biome fishing system. You can earn them by fishing and completing Fishing Milestones. Higher-tier fishing rods provide better Void Pearl bonuses, making it easier to collect more Pearls as you progress.
Exchange Void Pearls for Dark Matter Mutation
You can exchange Void Pearls for Dark Matter Mutation through the Alien Trade-In interface at the Alien Ferryman.
Follow these steps:
- Collect 1,750 Void Pearls.
- Find the Alien Ferryman.
- Open the Alien Trade-In interface.
- Spend 1,750 Void Pearls to obtain one Dark Matter Mutation consumable.
- Use the consumable on a placed Egg to try to apply Dark Matter Mutation.
Dark Matter Mutation has a 30% success rate per attempt.
Dark Matter is a new Mutation introduced in Update 12. It changes a pet's appearance and provides a 2.5x income multiplier.
5. How to Get Nebuloth Kraken in Cosmic Eclipse
Nebuloth Kraken is a new Divine pet introduced in the Alien Biome and one of the most valuable rewards in this update. It can only be obtained through the Cosmic Eclipse event.
When Does Cosmic Eclipse Start?
Cosmic Eclipse takes place every 30 minutes in Alien Lagoon.
The current observed event times are:
- Every hour at :25
- Every hour at :55
Each Cosmic Eclipse event has a global limit of only 750 Nebuloth Krakens.
Once all 750 Nebuloth Krakens have been caught, the event ends, and you must wait for the next Cosmic Eclipse to get another chance.
If you want to catch this Divine pet, enter Alien Lagoon and get your fishing rod ready before the event starts rather than rushing over after it appears.
6. How to Unlock the Secret Fusion Area
Besides fishing and collecting new pets, the Alien Biome also has a hidden area that requires 7 different Relics to unlock.
You can catch Relics while fishing in Alien Lagoon, where they are easier to obtain than in the regular Alien Biome.
You need to collect all seven different colors: Red, Yellow, Orange, Green, Blue, Purple, and Pink.
Keep in mind that you may catch duplicate Relics, so collecting all seven different colors can take some time.
New Fusion Rules: Obsidian Rex and Nebuloth Kraken
Once you unlock the hidden area, you will find a new fusion device. This fusion system involves two Divine pets: Obsidian Rex and Nebuloth Kraken.
According to the community-shared Fusion Rules, the multiplier depends on which pet has the higher income per second.
| Best Pet | Fusion Multiplier |
|---|---|
| Obsidian Rex | ×2 |
| Nebuloth Kraken | ×2.94 |
The multiplier is applied to the pet with the higher income per second, and all Mutations from that pet are also multiplied.
Therefore, if Nebuloth Kraken earns more money per second than Obsidian Rex, the fusion uses the 2.94x multiplier. If Obsidian Rex has the higher income, the multiplier is 2x.
The fusion creates a new alien-themed pet called Xenorath.
