Fix Pete's Machine

Paranoid Pete stands at Spawn by a radar booth, so talk to him and then tap the broken machine to his left. It opens the Alien Sensor Tracker, which is a pipe puzzle where you join Power to the Tracker.

1Count tiles from the top left, so row 1 is the top row and column 1 is the one next to Power.
2Row 2, column 1: turn the bend so it joins Power on the left and goes up.
3Row 1, column 1: turn the bend so it comes down and goes right.
4Row 1, columns 2, 3, and 4: turn the 3 straight pipes so they lie flat, left to right.
5Row 1, column 5: turn the bend so it comes in from the left and goes down.
6Row 2, column 5: turn the straight pipe so it stands up.
7Row 3, column 5: the cross piece works any way round.
8Row 4, column 5: turn the bend so it comes down and goes right, into the Tracker.
9The pipes glow green when they join, and Pete gives you the Signal Decoder.

Our board started like the first picture, so if yours is mixed up a different way, make the same path.

Alien Trade-In

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.

Alien Trade-In	Amount
Cost of 1 Alien Mutation	500 UFO Debris
Chance it gives Abducted	15%
Abducted Mutation bonus	x2.5 income
UFO Debris from 1 UFO	1,000 to 3,000
UFO Debris from a Rare UFO	4,000 to 5,000
Alien Mutations from 1 UFO	2 to 6
UFOs per hour	2, at :00 and :30
Rare UFO vault code	4827

An Alien Mutation only works 15% of the time, so at about 4 a UFO you can expect about 3 Abducted pets for every 5 UFOs.
Leftover Debris stays with you for the next UFO.
Debris stays on the ground after the day changes, so you can go back and grab Debris that you have not picked up.
