The Alien Biome in Steal an Egg doesn't hold just some of the best eggs you can get for your pen, it also hides some secrets. To unlock some of them, you first need to unlock the Alien Biome Door, but you can only do so by locating 7 relics. If you're unsure how to find them, then keep reading, as we can help you out!
How to Locate the Alien Biome in Steal an Egg

The Alien Biome in Steal an Egg is located right after the Enchanted Forest Biome and it include eggs of Legendary, Mythic, Cosmic, Secret, Eterna, and Divine rarity. These Eggs, which are some of the bets earning eggs in the game, aren't the only thing you can find here.
Inside the Alien Biome, you will see a locked door on the right. When you try to interact with it, it will tell you there are 7 missing Relics, and it will tell you how many you have found so far. If this is your first time interacting with the door, then the number is probably zero, and you most likely don't know where to look. Here's what you need to do and where to go.
How to Get Alien Biome Relics in Steal an Egg
The only way you can get Alien Biome Relics in Steal an Egg is by fishing. If you're thinking, well I'm in luck since I have the Fishing Rod from the Halloween event, I will sadly have to tell you that it's not going to work. If you try to fish with that Rod anywhere in the world, it will tell you that your speed isn't high enough.
The speed you need to match is the minimum requirement for the Alien Biome, which is 250B. If you don't have this speed, then your first focus is reaching it, as anything lower than that is basically locking you out of this entire questline.
If you do have the speed, then your next step is to interact with the Alien Ferryman at the Biome. He will give you your first Rod which you will use to fish in the waters of the Steal an Egg Alien Biome. Sadly, you can't fish anywhere else. Trust me, I've tried, it doesn't mater if that water looks like water in the Angel Biome, when it comes to fishing, it is fake!

It will be annoying for a bit having to go back and forth to this far away biome every time night falls, but that will be solved quickly. As soon as you reach a certain level of fishing mastery, you will unlock the ability to travel to the Lagoon with the Alien Ferryman.
Much like the Secret Fishing Area you could get to through the Phantom Express during the Steal an Egg Halloween event, the Lagoon also allows you to just keep fishing no matter if it's day or night. However, you will still get notifications when new Eggs respawn and if you see one you may want, run to the Ferryman to take you back to the Main World. He will spawn you at the start of the World and not at the final biome, which is bad customer service, so just count that into your Egg stealing planning.
While fishing, you will also pull up lots of Void Pearls as well as Alien Biome Eggs. It will take you some luck before you can get all of the Steal an Egg Alien Relics. They are all a different color, and you only need to fish them out once each. When you have a Relic, go to the Portal Door and interact with it while holding the Relic. It will go inside the Door and make you one step closer to opening it.

Another good thing is that, just by fishing, you will unlock Fishing Mastery. One of the rewards you get at 100 caught Fish is the Kraken Rod, an upgrade for the regular Rod that gives you a 1.1 Luck Boost, hopefully enough to have you collecting all of the Relics quickly. If not, the Lunar Rod upgrade is at 750 Fish caught.
Why Don't I See My Relic in Steal an Egg?
If your Relic that you just fished out is suddenly missing, don't panic! It may be that the game hasn't registered it yet. It happened to me and I thought I would have to fish out the Yellow Relic once again. However, the Relic is in your Inventory already, it may just take a minute or two to register. You can find any Relics you catch in the Gear section of your Steal an Egg Inventory.
