Your hand lingers over one of the gunk-covered walls. What the hell even is this stuff? You ignored it in lieu of doing other tasks but it's like nothing you've seen before.

Every single surface (except your old computer) has been caked in this dry yet sticky crust. It almost reminds you of the shit that caked the walls of your aunt's house. It's probably SOMETHING adjacent to a nicotine stain but your gut tells you it can't just be that.

You scrap off some of the substance with your ID card. You rather not get this shit underneath your fingernails. It almost seems to liquify right in front of your eyes, turning into a sticky paste that clings to your plastic card.
You raise the card up to get a better look at the substance.

It's. It's moving.
It wasn't noticeable at first but you can definitely see some slight movements from the brown, cigarette-smelling paste. It twitches and pulses with an odd, irregular rhythm. Almost like it's alive.
The paste slowly spreads across your ID card like it's jam being spread on bread. You press your finger against it and almost immediately, the spreading stops. The gunk recedes away from your finger until there's an inch of distance between the two.

When you lift it back up, it begins to spread again.
Hm. You take your floppy disk and you press the corner of it against the gunk. It tries to spread onto the disk - Odd. What makes your finger different? You yank the disc away before it can get a solid grip on the disk.

You glance back at the floor you took the gunk from. It's slowly spreading to fill up the hole you left behind. It's taking a lot of time to fill up the gap while, at this point, your ID card is already gunked up.
You easily manage to peel off the still wet gunk from your card before it can corrode.

You plant your foot on the ungunked part of the floor. The gunk's spread is not halted and you have to yank your foot back before it decides your shoe was a prime target to gunk up.

Alright. So it's obvious this gunk is alive. With how it's moving, it most reminds you of slime mold. That weird, sticky shit you'd see clinging to tree bark.
You think you might've seen something that'd fit this better but the memory evades you.

It seems inert until it's damaged and for whatever reason, it's afraid of being directly touched while it's spreading. You're not sure why your finger caused a reaction and not your foot but this is the best you can get with what limited resources you got.

It stinks like nicotine too so something that'd remove nicotine stains would also help to remove it.
You think you heard that vinegar is pretty good at getting mold out of stuff. You do know there's also some cleaning supplies made specifically for getting smoke odors out of things - You'll have to see if you can buy that later.
