Paranoid Pete

Paranoid Pete stands at Spawn, and his timer ran from October 31 to November 2. The UFO Invasion started when it hit zero.

Talk to him once to start, then come back to him with UFO Debris to trade.
See Paranoid Pete's Signal for the timer.

Pipe Puzzle Answer

Pete's machine is broken, so tap it to open the Alien Sensor Tracker. Turn the tiles until power runs from Power to the Tracker, and Pete gives you the Signal Decoder.

Count tiles from the top left, so row 1 is the top row and column 1 is the one next to Power.
Row 2, column 1: turn the bend so it joins Power on the left and goes up.
Row 1, column 1: turn the bend so it comes down and goes right.
Row 1, columns 2, 3, and 4: turn the 3 straight pipes so they lie flat, left to right.
Row 1, column 5: turn the bend so it comes in from the left and goes down.
Row 2, column 5: turn the straight pipe so it stands up.
Row 3, column 5: the cross piece works any way round.
Row 4, column 5: turn the bend so it comes down and goes right, into the Tracker.
The pipes glow green when they join, and Pete gives you the Signal Decoder.

UFO Event Steps

A UFO spawns every 30 minutes (at :00 and :30) and leaves about 5 minutes later.

Wait for the banner at the top of the screen, which says A UFO has been sighted and how long until it leaves.
Run down the map, away from Spawn, while the Signal Decoder screen shows STRANGE SIGNAL and a bar at 0%.
Keep running, as the bar goes up when you get close. At 100% it says BIOME FOUND and names the biome, which can be any biome (even the second one).
Look for eggs with a green UFO glow, as those are the Abducted eggs. There are always more than 3 of them, and they are not always near the UFO. The screen says Find 3 suspicious eggs.
Steal one and run into the UFO's beam, which you only need to touch. The screen then says SIGNAL RECEIVED, 1/3 eggs delivered.
Do the same with 2 more Abducted eggs.
After the third egg, stay in the beam so that UFO Debris drops down, then walk over the Debris to pick it up. Debris stays on the ground after the day changes, so you can go back and grab Debris that you have not picked up.
Run back to Paranoid Pete at Spawn and talk to him (the game calls him the Alien Chaser here).
Press TRADE, as each trade takes 500 UFO Debris and gives you 1 Alien Mutation.
Use the Alien Mutation on an egg, which has a 15% chance to give the pet the Abducted Mutation.

Alien Trade-In

Paranoid Pete trades 500 UFO Debris for 1 Alien Mutation. To clarify, Alien Mutation is a usable item that has a chance to give the Abducted Mutation on your pet with a 15% chance on use/consumption.

One UFO gives 1,000 to 3,000 UFO Debris (more for eggs worth more), which buys 2 to 6 Alien Mutations.
Each Alien Mutation has a 15% chance to work, so at about 4 a UFO you can expect about 3 Abducted pets for every 5 UFOs.
Debris stays on the ground after the day changes, so you can go back and grab Debris that you have not picked up.
Abducted gives x2.5 income and stacks with other mutations, like Rainbow.

Rare UFO

Each UFO has a 10% chance to be a Rare UFO, which spawns in every server at the same time so everyone gets a turn.

When the Rare UFO spawns, a green beam teleports you up into it.
You are inside the UFO now, and the INSIDE THE UFO timer at the top counts down.
Smash the big coloured capsules, as each one has UFO Debris inside.
Smashing all of them gives about 4,000 to 5,000 UFO Debris.
Find the yellow sticky note on the desk by the screens, which says 4827.
Go to the locked vault door, tap its keypad, type 4827, and press OK.
The vault opens and gives you the Alien Staff, an Uncommon weapon.

The code was 4827 on Nov 3, 2026, so check the sticky note again if it stops working.
