Steal An Egg UFO Invasion arrived in Roblox on November 2, 2026. Update 11 introduces Paranoid Pete, his damaged machine and a Signal Decoder used to locate UFOs every half hour. Your main task is to deliver three eggs with the Abducted effect to earn UFO Debris.
Rare UFOs have another reward tucked away inside: the Uncommon Alien Staff. It comes from a locked vault, not the normal egg-delivery objective. Here’s how to get through both parts of the event.
How to start Steal An Egg UFO Invasion
Find Paranoid Pete at Spawn and talk to him. His damaged machine has a pipe puzzle connecting Power to the Tracker. Work through the pipe pieces to complete that connection, then finish the repair. Follow the endpoints shown on your own screen rather than assuming a copied screenshot matches your puzzle.
Once the machine is working, Pete gives you a Signal Decoder. Keep it ready for the next sighting. UFOs can appear in different biomes, so you won’t find every ship in the same spot. Getting this tool is your first step in Steal An Egg UFO Invasion.
Steal An Egg UFO Invasion UFO spawn times
UFOs arrive at :00 and :30 past every hour. If you miss one at 9:00, the next is scheduled for 9:30. When the sighting announcement appears, equip your Signal Decoder and move through the map. The signal bar increases as you get closer; at 100%, it identifies the biome where the UFO has appeared. Watch the event timer while you search.
Look for eggs with a green UFO glow. Those are the ones marked with the Abducted effect. They aren’t necessarily beside the UFO itself, so check further along the map instead of waiting beneath the beam.
How to collect UFO Debris in Steal An Egg UFO Invasion
The UFO wants three eggs with the Abducted effect, not just any three eggs. Pick up one green-glowing egg and run into the ship’s beam. The delivery counter should move to 1/3. Repeat with two more eggs, one at a time. After the third, stay in the beam to trigger the UFO Debris drop, then walk over the Debris to collect it. The amount you receive varies between encounters.
The eggs you deliver must already have the Abducted effect. The Alien Mutation crystal sold by Pete is a different item that you buy later with the Debris you’ve earned.
Steal An Egg UFO Invasion Alien Mutation price and chance
Go back to Pete at Spawn, talk to him and select Trade to open Alien Trade-In. One Alien Mutation crystal costs 500 UFO Debris. Use it on an egg for a 15% chance to give the pet the Abducted mutation. You aren’t guaranteed a successful result every time you spend Debris.
When the mutation applies, it gives the pet a 2.5x income multiplier. That’s the boost, not the chance of getting it. The 15% success rate belongs to the crystal, and doesn’t tell you how often a rare UFO appears.
How to get Alien Staff in Steal An Egg UFO Invasion
A rare UFO can pull you inside through its green beam. Delivering three eggs to an ordinary ship won’t automatically transport you there. Watch for a rare encounter, then use the beam when it offers entry. This is the part of Steal An Egg UFO Invasion you need for the Staff.
Once aboard, check the countdown. You can smash the coloured capsules for extra Debris, but if you want the weapon, find the desk near the screens. A yellow note there has the four-digit code for the Alien Vault. Go to the vault keypad, enter the code and press OK. The reward is Alien Staff (Uncommon). Get there before the interior timer runs out.
A recorded visit on November 3 showed the code 4827. Read the yellow note in your own ship before entering it, though. That recorded password is not proof the code never changes, and your own on-screen countdown is the one to follow.
Steal An Egg UFO Invasion common questions
UFO missing? Wait until the next :00 or :30 encounter, equip the Signal Decoder and follow the signal. The UFO doesn’t have one permanent spawn position.
Eggs not counting? The objective needs three eggs carrying the Abducted effect. Ordinary eggs will not satisfy it.
Do all UFOs have Alien Staff? No. You need an opportunity to enter a special ship, then you must open the Alien Vault while its interior event is running.
Is the Alien Biome live? Not yet. Steal An Egg UFO Invasion is Update 11, which arrived November 2. The full Alien Biome is a separate Update 12 scheduled for Saturday, November 7 at 4pm GMT. You can complete Pete’s current quest ahead of the November 7 release, but the developer hasn’t said it is mandatory to enter the new biome.
For the Steal An Egg UFO Invasion, the best place to start is still Pete’s machine at Spawn. Once you have the Decoder, the next half-hour sighting is your chance to bring in the right eggs and start saving Debris for a crystal.
