A fun challenge you can do alone or with friends to unlock achievements through BATIM Chapter 3 and Chapter 4, and experience tons of spooks!

Introduction
Welcome to the guide for the Happy Boris Challenge! This is a BATIM Chapter 3 - 4 challenge that focuses around everyone's favorite wolf - Boris. In this challenge, you will make sure to give your Boris the best life he can possibly have throughout the time of knowing him. You can do this challenge alone, or with your friends! It will also act as a walkthrough in finding some achievements throughout these chapters. I hope you enjoy!

Step 1 - Acquire the Bone
The bone is the first and most crucial step for this challenge. As soon as you feed your Boris, send him outside to wait. Go back into the bedroom and find a bone sitting under his hammock. Even though it doesn't shine, it is indeed collectable. Go back to your Boris, and "Knick-Knack Paddywhack", give the poor doggie a bone.

Step 2 - Supply food
Your Boris is bound to be hungry throughout your treacherous adventure through the studio. Make sure to keep him fed by collecting every last can of Bacon Soup you can find. A hungry Boris is a sad Boris. Bring Home the Bacon!

Step 3 - Supply a light source
The darkness of Joey Drew Studios is probably one of the scariest things there, and you don't want your Boris to be shaking alone in the dark, right? Do not let Boris shake in the dark, he has very spooky nightmares. Extreme spook.

Step 4 - Don't support the angel
The angel wants your Boris all to herself! You must keep away from her as much as you can. Do not walk the way of the angel, that only shows your Boris that you support the one out to get him. You must walk "The Path of the Demon".

Step 5 - Never leave him alone
If you go down, Boris is basically a flashing target for whatever took you. Your Boris is a very defenseless wolfo, don't leave him stranded by dying on the job, he still needs your protection.

Step 6 - Acquire the most powerful weapon
You need something to protect your best buddy with, right? Well, lucky for you, you have the power to get "Blazing Metal". All you have to do is at Jacksepticeye's Sean Flynn's tape recorder, turn the ink blob into the shape of the original Ink Machine. Continue the previous steps, and if you did it right, you will have unleashed the Tommy gun.

Step 7 - Your (third) biggest threat
You have the angel, who hides behind class. You have the demon, who has a deadly touch. And then you have the Projectionist, who can easily find their way to the elevator where your Boris is. Make sure there's no risk of that happening, and reveal "Norman's Fate". Shoot the Projectionist and bring them down to the ground.

Step 8 - Entertainment (optional)
Boris left by himself in the elevator isn't very fun for him. What IS fun however is bringing a bouncing barrel inside with you! With the Tommy gun, get a movable barrel inside the elevator. As you travel around with the elevator, the barrel will bounce around with you two. Now picture that: A bouncing barrel in an elevator with video game physics. Now doesn't that just sound like barrels of fun? (Editor's Note: Unsure if this is still a possibility with the recent Chapter 4 update, if not, than you can have a free pass).

Step 9 - Search and rescue
What?! The angel took your precious Boris boy? We can't let her get away with this! Go through Chapter 4 without dying once, rescue your friend as fast as possible!

Step 10 - Give an advantage
Okay, so, unfortunately, as most of you probably know already, we can't save our Boris. However, we can make sure we put him through as little pain as possible. Before you head into the haunted house, go back to the fourth area. On the second floor, go around to where you turned the lights off on the Projectionist. You'll see a case, open it up, and see that there is a turn dial for the Gent Machines. Collect it, and you'll give yourself an "Unlikely Victory" by fighting Boris with a plunger.
