After returning to the Slums in stage 6 (The Slums Part 2), one of the mandatory tasks will be obtaining a poncho for Elliot from the Elliot Programming building. This page of the guide explains how to craft this item by working with other robots.
The full walkthrough for the second visit to the Slums (stage 6) can also be found in our walkthrough.
Meeting Elliot in chapter 6
As a reminder, Elliot works in the Elliot Programming building. The screenshot depicts its entrance. You have to interact with the door and start scratching it until Nestor the robot lets you inside.
Elliot can be found on the upper floor. The main purpose of the visit is to fix the Tracker. Elliot will do it if you bring him something to get warmer - a poncho.
You could already obtain a poncho in Chapter 4 by doing some non-obligatory activities. Otherwise, you must perform all the actions listed below.
Getting the poncho
Before you can get the poncho, you must first get the Super Spirit detergent .
There is a closed Super Spirit Laundry near the central part of the slums, and you need to get inside.
Your task is to provoke the laundry owner to leave the building. Near the laundry room, you will find protruding objects on the walls of the buildings. Use them to reach the rooftops.
There are 2 robots on the roof of the laundry room and one of them is throwing paint cans. You have to distract it and meow when it is making the throw. It doesn't have to be done once - you can increase your chances by meowing several times in a row.
A successful meow will trigger a cut-scene of dropping the paint can. It will crash right in front of the laundry entrance.
The owner will leave the laundry and stay outside - you don't have to hurry. Go down any way you like and use the newly unlocked entrance to the laundry.
The key quest item in the laundry room is the Super Spirit detergent pictured in the attached screenshot.
Bring the detergent to the local merchant Azooz - his stall is near the central part of the slums. It sales 3 items - there are Electric Cables in the middle, which you must choose in exchange for the detergent you have (choose this item from your inventory).
Explore the surrounding streets and you'll encounter Grandma - you can give her the electric cables that you bought from Azooz.
Grandma will make you a poncho from the cables for free. Now, you can return to Elliot and give him the item. As a reward, you will receive a Fixed Tracker from him.
