How to Unlock the Alien Biome Gate in Steal an Egg Guide
The Alien Biome in Steal an Egg has a hidden gate that leads to a special area called the Alien Fusion Chamber. However, opening it requires more than simply finding the entrance. Players must first complete the Alien Ferryman’s quest, gain access to the Alien Lagoon, and collect seven different Relics by fishing. These Relics are quite rare, so unlocking the gate may take some time. Once all seven are collected and placed in their correct positions, you can enter the Fusion Chamber and combine two Divine Pets to create an Alien Egg.
Where to Find the Alien Biome Gate
The Alien Biome Gate is located on the right side of the Alien Biome, near the Alien Ferryman. You will need seven unique Relics to unlock it, with each Relic having its own color and designated position.
However, you cannot immediately enter the area where these items are found. First, you must reach 250B Speed to access the Alien Ferryman’s quest. After meeting this requirement, you can start working toward unlocking the secret Lagoon area.
How to Complete the Alien Ferryman Quest

The Alien Ferryman will ask you to catch 20 fish in the Alien Biome. This is the first requirement you need to finish before gaining access to the Alien Lagoon.
You can catch fish from the water around the Alien Biome. If you do not own the Halloween Fishing Rod, the Ferryman will provide you with an Alien Rod so you can complete the objective.
Follow these steps to finish the quest:
- Reach 250B Speed to unlock access to the Ferryman’s quest.
- Find the Alien Ferryman in the Alien Biome.
- Interact with him to receive the fishing objective.
- Take the Alien Rod if you do not have the Halloween Fishing Rod.
- Cast your fishing line into the nearby water.
- Catch 20 fish to complete the quest.
Once you have caught all 20 fish, return to the Alien Ferryman. You can then interact with him to travel to the Alien Lagoon.
How to Enter the Alien Lagoon
The Alien Lagoon is a secret fishing area that becomes available after completing the Alien Ferryman’s quest. It is important to understand that this location is separate from the Alien Biome Gate. You need to visit the Lagoon to collect the Relics required to open that gate.
After completing the quest, speak with the Ferryman and choose the option to travel to the Lagoon. Once you arrive, you can start fishing in the nearby water to obtain several different rewards.
Items you may find while fishing include:
- Void Pearls: Special items that can be obtained from the Lagoon.
- Alien Eggs: Eggs available through the fishing activity.
- Mutations: Consumables and other mutation-related rewards.
- Relics: Rare collectibles needed to unlock the Alien Biome Gate.
The main objective here is to collect all seven unique Relics. You can continue fishing to gather other rewards while working toward completing the collection.
How to Fish for All Seven Relics
There are seven different Relics hidden in the Alien Lagoon, and each one has a unique color. You must collect every type before you can unlock the Alien Biome Gate.
Unfortunately, there is no confirmed drop rate for these Relics. They are considered rare fishing rewards, meaning you may need to spend quite a bit of time casting your rod before finding all seven.
The fishing mechanics are similar to those used during the Halloween event. You do not need to learn an entirely new system to start collecting Relics.
Follow these steps to fish:
- Stand near the water inside the Alien Lagoon.
- Click on the water to cast your fishing rod.
- Wait until a fish or item takes the bait.
- Repeatedly click the M1 button to catch it.
- Continue fishing until you obtain all seven Relics.
You can also make progress toward Fishing Milestones while doing this activity. These milestones provide additional rewards, including new Fishing Rods, Rare Pets, and Mutation Consumables.
Since Relics are rare, it is worth continuing to fish even when you receive other items. Every fishing attempt can provide another reward while bringing you closer to completing the collection.
Nebuloth Kraken Boss Event
Besides collecting Relics, the Alien Lagoon also features a special boss-catching event. Every 30 minutes, players across the entire game can participate in an event to catch the Divine Nebuloth Kraken.
This is a limited global catch event, so players need to compete against everyone else participating in the same event. Only 750 Nebuloth Krakens are available worldwide during each 30-minute event.
Once all 750 have been caught, no more Nebuloth Krakens can be obtained until the next event begins. This makes the event time-sensitive, especially if you want to collect the Divine Pet for your Alien Fusion Chamber.
If you plan to obtain the Nebuloth Kraken, keep an eye on the event schedule and try to participate as soon as a new round starts.
How to Unlock the Alien Fusion Chamber
After collecting all seven Relics, return to the Alien Biome Gate near the Alien Ferryman. You will need to place each Relic in its matching position to complete the unlocking process.
Make sure you have all seven different colors before returning to the gate. Once every Relic has been placed correctly, the Alien Biome Gate will open and reveal the Alien Fusion Chamber.
This secret room contains a special fusion feature that allows you to combine two Divine Pets. The goal is to create an Alien Egg, which can hatch into a potentially stronger Divine Pet with high base income.
The two Divine Pets required for this fusion are:
- Obsidian Rex
- Nebuloth Kraken
You need both pets to use the Alien Fusion Chamber. After obtaining them, interact with the fusion feature and combine the two Divine Pets to receive the Alien Egg.
What Does the Alien Egg Do?
The Alien Egg is the main reward available from the Alien Fusion Chamber. Instead of being a regular egg obtained through normal gameplay, it is created by combining Obsidian Rex and Nebuloth Kraken.
The Alien Egg has a chance to hatch into a better Divine Pet with high base income. This makes the secret gate worth unlocking, especially for players who want to improve their pet collection and increase their income.
However, getting the Alien Egg requires several steps. You must complete the Ferryman’s quest, collect seven Relics, unlock the chamber, and obtain both required Divine Pets before you can perform the fusion.
Unlocking the Alien Biome Gate in Steal an Egg requires completing the Alien Ferryman’s quest and collecting seven unique Relics from the Alien Lagoon. Start by reaching 250B Speed, catch 20 fish to unlock the Lagoon, and continue fishing until you have every Relic.
Once the gate is open, you can access the Alien Fusion Chamber and combine Obsidian Rex with Nebuloth Kraken to create an Alien Egg. This egg gives you a chance to obtain a stronger Divine Pet with high base income, making the entire process an important activity for players looking to improve their collection.
