SCP-5528

“Laughing Gas”
Description:
SCP-5528 is a small steel two (2) foot tall canister marked “Laughing gas”. By the amount used from testing, SCP-5528 has no bottom. An estaminet of over five (5) kilograms of gas has been used. A contaminant in the gas makes people laugh.

After the compound enters the body, the “host” then begins to laugh uncontrollably. After about [EXPUNGED] minutes the host will then mutate into SCP-5528-1. SCP-5528-1 is mutated in many ways, adding mouths, arms, legs, teeth claws/nails, teeth/fangs, armor, and super human strength and speed. The canister is virtually bullet proof and cannot be punctured. This helps in neutralizing SCP-5528-1 without having to worry about puncturing the canister.

SCP-5528 can seemingly infect anything. It has been tested with a dog, snake/cobra, cat, and a human. (See experiment logs SCP-5528-A through SCP-5528-D.)
Special Containment Procedures:
SCP-5528 is held in a 20mx20mx20m Airtight containment room with an attached decon room. The room must be filtered every week and checked for cracks in both the container and room.
Anybody who enters the room must be decontaminated and checked for any toxins or contaminants related to the laughing gas.

The mutations of SCP-5528 are almost indestructible and require the highest caliber weapons, though electric weapons (such as the Micro H.I.D.) seem to be extremely effective. Cryogenic and incendiary weapons are also effective.

TEST VIDEO LOG: SCP-5528-A
<BEGIN LOG>
One dog of the [EXPUNGED] breed has been deposited in the containment area. D-27781 in a hazmat suit has been ushered into containment area to open the container for fifteen (15) seconds.
D-27781: (From inside containment) ten (10) seconds, right?
Dr.(Blur): Fifteen (15) seconds.
D-27781: Okay. (D-27781 is seen opening the container from by twisting the valve, as he is whispering) 1- 2- 3- 4- 5- 6- 7- 8- 9- 10- 11- 12- 13- 14- 15 done.
At six seconds, the dog is seen already jerking and making a laugh like sound.
D-27781: Wha- What the fuck! What are you doing to the dog? Sick Fucks!
D-27781 sprints out of the containment room. As he leaves, he attacks one of the guards.
Guard: (in the background) D-27781 designated for termination! (Several gunshots are heard) Get this shit head’s body out of here.
Continue with testing and check for bullet holes in the wall.
(After several minutes, the dog is seen mutating.)
Subject is mutating, gaining several limbs. Mouths have grown over the body. The subject has stopped laughing and is now turning violent, slashing at the wall with overgrown nails. Subject has now broken into the decon room. Terminate test!
Guards enter the room, one holding a Micro HID, the others holding high caliber rifles.
Front guard: Go die in hell. Open fire!

Dr.█████: Who opened the valve?
Guard: A D-class. They put him in a hazmat suit. He also carried a cat in with him.
Dr.█████: How did the cat… uh, react, to SCP-5528?
Guard: The fucking cat grew to the size of a deathclaw from Fallout. It was one (1) foot tall before infection, and it grew to seven (7) fuckin’ feet!
Dr.█████: Did it turn hostile?
Guard: Bet your Ass! He clawed through the containment room! We grabbed the Micro H.I.D. and lit it up!
Dr.█████: Did it react, flinch?
Guard: Fuck no! Someone brought in a 50. cal and it barely even punctured the body. We had to grab a M80 Vulcan to chew through it. It finally fell to the ground. It sat there and twitched for twenty minutes. While people were cleaning up the room, the thing exploded! I was lucky that I had my mask on. I shot everyone up before they even started laughing.
Dr.█████: Autopsies on deceased personal exposed to SCP-5528 shows many unknown chemicals and organs. One organ is believed to make spores that leave from the lungs when exhaling. Would you like to continue to monitor SCP-5528 throughout tests?
Guard: Unless you're going to terminate it next time, I’m out.
