To get the Abducted mutation in Steal an Egg on Roblox, you need an Alien Mutation crystal from Paranoid Pete, and each one costs 500 UFO Debris. You earn that debris during the UFO Invasion event by finding a UFO and delivering three suspicious eggs. Each crystal has a 15% chance to apply Abducted to an egg, and a successful application gives the hatched pet a ×2.5 income multiplier. In Steal an Egg, every pet you hatch earns income, and a mutation is a bonus that raises it.

How to Unlock the Signal Decoder From Paranoid Pete
Everything starts with Paranoid Pete. Talk to him to begin the UFO questline, then repair the broken alien communications machine beside him. That repair gives you the Signal Decoder, the tool you need to track a UFO, so this step has to come first.

- Speak to Paranoid Pete to start the UFO questline.
- Open the Alien Sensor Tracker puzzle at his machine.
- Rotate the tiles until a connected path links the power source to the tracker.
- Finish the connection to receive your Signal Decoder.
The tile layout can vary from one attempt to the next, so don't memorize a fixed answer. Start at the power source, follow the tiles toward the tracker, and rotate each piece as you go. Once both ends are linked, the puzzle is complete.
How to Find a UFO and Collect UFO Debris
UFO Invasion encounters happen every 30 minutes on each server, at :00 and :30. The Signal Decoder locates the active UFO, so use it once an encounter starts. Every player on the server can use the decoder to find the ship.
- Wait for an encounter to begin at :00 or :30.
- Use the Signal Decoder to locate the active UFO, then follow its location on the map to the ship.
- Watch for the "UFO FOUND!" objective, which shows an egg counter and a countdown.
- Find three suspicious eggs under the ship's light and steal them from any biome.
- Bring all three back to the ship before the countdown ends.
- Pick up the UFO Debris the ship drops.
The suspicious eggs are the event's own eggs, the ones with the ship's light falling on them. The objective counts only these, so ordinary eggs won't work. Watch the counter move from 0/3 to 3/3 as you go, so you know the delivery is on track.
After you hand over the eggs, the screen shows "Pick up your reward!" The debris is a separate pickup, so don't leave until you've grabbed it. Keep completing deliveries on later encounters until you have 500 UFO Debris.
How to Trade UFO Debris and Apply the Abducted Mutation
Return to Paranoid Pete and open Alien Trade-In. The exchange is 500 UFO Debris for one Alien Mutation crystal. The shop calls the item Alien Mutation, and the mutation it applies is called Abducted, so you're looking for one item and one mutation.

- Speak to Pete and open Alien Trade-In.
- Check that your UFO Debris balance is at least 500.
- Trade 500 debris for one Alien Mutation crystal.
- Use the crystal on an egg and follow the in-game prompt that appears.
Each crystal has a 15% chance to apply Abducted, and buying one doesn't guarantee the mutation. You may need several crystals before one of your eggs gets it, so plan your debris around how many you want to buy.
When the mutation applies, the hatched pet earns a ×2.5 income multiplier, so it makes 2.5 times its normal income. The 15% chance only decides whether the mutation lands on the egg. It isn't an income multiplier, and it doesn't change the strength of the multiplier once the mutation is applied.
