Mad father walkthrough cell
After filling the bucket and Aya is shown walking with it, go back in the Reception Room and use it to put out the fire, then enter the fire place.
Go throught the passage, to the edge of the pond and use the Wood Bucket. Walk through where the torn painting was on the wall, if there is a normal painting there, interact with it and move it. Then, make your way to the Reception Room (the bottom left hallway from the Entrance Hall, door on the right). (The bucket is located where Aya is facing in this screenshot) Start walking to the right until something falls behind you, turn around and pick it up to get the Eyeball Bottle. Examine the shelf on the far top-left (you will see an image). In the Taxidermy Room (East Hall -> Stairs to Basement -> Outside Laboratory -> door on the bottom), pick up the Wood Bucket by the door. THE 'BRANDING IMAGE', as Steam calls it (essentially the guide's "profile picture") IS NOT MINE, I downloaded it from here: You can spot these achievements by the first line of text directly under them saying "story-related, can't be missed" or something similar ( shocking, I know :p). I will try to make the event as cryptic as possible while it still being able to be easily understood. There are story-related achievements that will pop after a certain event. INFORMATION REGARDING SPOILERS: There will be no extreme or major spoilers in this guide.

If you have any questions, about any element/part in the game, feel free to ask, otherwise, thank you for using the guide and I hope it helped! I am doing this guide based off memory of my playthrough, PLEASE point out if an achievement description is wrong, if a more in-depth explaination is necessary, or anything else. This is the first guide I have made, if there are mistakes of any sort, please inform me of them so I can fix them.
Also, read the "Love Letter" section before beginning your second playthrough if you did not get this achievement during your first playthrough (which you likely missed, since it is intended to be achieved during the second playthrough). If you are checking this for the achievement(s) "The Promise", or "Familiar Face", read the notes at their sections first. It is also recommended to follow a Gem guide since you need to collect them all for an achievement and I have not covered acquiring them all yet in this guide. This guide contains the information needed to unlock every achievement (and some gems along the way) for Mad Father, organized by in-game progression.
