How to Get the Signal Decoder in Steal an Egg (2026)

To get the Signal Decoder in Steal an Egg, talk to Paranoid Pete, interact with his broken machine, and finish the pipe puzzle by linking the pipes into one unbroken path. Pete then hands you the Decoder as a reward. That is the whole unlock, and you need it before you can join the UFO Invasion that arrived with Update 11 on November 2, 2026.

The catch is that guides disagree on a few details: where Pete stands, whether every player sees the same puzzle, and whether a Speed requirement applies. This guide marks what the official changelog confirms and what is still single-sourced.

Where Is Paranoid Pete Standing?

Most guides put Pete at spawn, with his communication machine on the table to his left. One outlet places him near the Trails stand instead. Both descriptions point to the starting hub, so if he is not right in front of you, look around the spawn area for the NPC standing beside a machine and a board of UFO notes.

Signal Decoder unlocked message after repairing Paranoid Pete's machine in Steal an Egg

Pete is a quest NPC, so you must talk to him first. Walking up to the machine without accepting his objective may not start the puzzle, so open the dialogue before anything else.

How to Solve Pete’s Pipe Puzzle, Step by Step

Walk up to Pete and talk to him to accept the repair objective.
Interact with the machine on the table beside him.
Link the pipe tiles into one continuous route from the top-left corner to the bottom-right corner.
When the path connects, the machine powers on.
Pete rewards you with the Signal Decoder, which you can equip when a UFO is active.

Expect the whole thing to take a minute or two. That sounds small, but the UFO only appears every 30 minutes, so finish it before the next :00 or :30 mark if you want to catch a window right away.

Why Your Puzzle May Not Match the Guides

Here is where guides split. One source describes connecting pipes from corner to corner. TechWiser describes connecting power lines to a Signal Tracker and says each player gets a different tile layout, so there is no fixed solution to copy. A third tracker calls it the Alien Sensor Tracker tile puzzle.

These are probably the same puzzle described three ways. So treat “top-left to bottom-right” as your goal, not a memorized pattern. If your layout looks different from a screenshot, that is expected. A useful habit with any tile puzzle: work backward from the bottom-right end as well as forward from the start, because it is easier to spot the one tile that bridges both halves.

Do You Need 18 Million Speed to Get the Signal Decoder?

One outlet, lists at least 18,000,000 Speed before you speak to Pete. That number does not appear in the patch notes, and no other major guide repeats it for the unlock itself, so treat it as unconfirmed.

The practical move: try the puzzle first. If Pete does not offer the quest, Speed may be the gate, and only then is it worth training. Where Speed definitely matters is after you have the Decoder, because each biome’s guardians chase you while you carry eggs to the spaceship.

What the Signal Decoder Actually Does

The Decoder is a tracking tool, not a one-time key. When a UFO spawns at :00 or :30, equip it and it shows which biome the spaceship is in. From there the loop is:

Find the UFO with the Decoder.
Deliver three eggs with the Abducted effect.
Collect UFO Debris when the ship leaves.
Trade 500 Debris to Pete for an Alien Mutation consumable (15% chance of the Abducted mutation).

The full delivery route, Debris math, and mistakes to avoid are covered in our Steal an Egg UFO event guide. One more reported detail: a Rare UFO with a 10% spawn chance may teleport you inside once you locate it. That comes from a single tracker, so do not plan around it.

Signal Decoder, UFO Code, Alien Mutation: Which Is Which?

These get mixed up constantly, and the mix-up wastes time.

Item	What it is	How you get it
Signal Decoder	Equipment that locates the UFO	Pete’s pipe puzzle
UFO Debris	Reward currency	Delivering three Abducted eggs
Alien Mutation	Consumable for eggs in your pen	500 UFO Debris from Pete
“UFO code”	Reported in-game vault password	Read inside the ship, unconfirmed

Alien Trade-In menu offering one Alien Mutation crystal for 500 UFO Debris with a 15 percent success chance

The “UFO code” is not a Roblox redeem code. Steal an Egg has no code system, so skip any site promising a code list.

What to Do Right After You Unlock It

Be ready for the next window. The UFO spawns on a strict half-hour rhythm, much like the Rift Event, so you can plan both timers together.
Save Debris for a good egg. A 15% chance is a gamble, so aim it at your most valuable unhatched egg. The all pets list shows rarity and income if you need help choosing.
Keep training Speed. The separate Alien Biome is scheduled for Saturday, November 7, 2026 at 16:00 UTC, and earlier biomes have been Speed-gated.
Trace the lead-up. The UFO teaser first appeared around the Jonas Brothers concert, and Update 11 is the latest entry in the patch timeline.
Check the official page. Patch notes and any Pete changes show up on the Steal an Egg Roblox first.

Frequently Asked Questions

Talk to Paranoid Pete, interact with his broken machine, and complete the pipe puzzle by connecting the pipes into one path from the top-left corner to the bottom-right corner. Pete then rewards you with the Signal Decoder. Some guides say each player gets a different tile layout, so aim for the connected path rather than a fixed pattern.

Most guides place Paranoid Pete at spawn, with his machine on the table to his left. One outlet says he is near the Trails stand. Either way, check the starting area for the NPC standing next to a communication machine and talk to him first to start the quest.

You need the Signal Decoder from Pete’s puzzle. One outlet lists at least 18,000,000 Speed to take part, but the patch notes do not mention it and no other major guide confirms it, so treat it as unverified. Try Pete’s quest first and rely on the in-game prompts.

A UFO appears somewhere on the map at :00 and :30 of every hour. Equip the Signal Decoder when it spawns and it shows which biome the spaceship is in. Then deliver three eggs with the Abducted effect to the UFO to earn UFO Debris.

One Alien Mutation consumable costs 500 UFO Debris, bought from Paranoid Pete. Apply it to an egg in your pen for a 15% chance of the Abducted mutation, so save it for an egg that is worth the gamble.
