Per 
The D-0-SD Underground Facility's main objective is to contain SCPs discovered, captured by the Facility, and may hold SCPs assigned to be contained at the Facility by the Foundation.
Item #: SCP-AAAA
Object Class: Euclid
Special Containment Procedures: SCP-AAAA is to be kept in a 40x40x70m concrete chamber
inside D-0-SD Special underground containment facility at Site D-0-██ in Hungary. The inside of the chamber has 4 sections (4x4m) designed as a sleeping area for the selected D-class personnel.
4 (four) D-class personnel are assigned to live inside the chamber. These personnel are reffered to as SCP-AAAA-A (D-003-0, D-024-0, D-071-0 and D-101-0)
All 4 instances of SCP-AAAA-A can communicate freely with security Personnel guarding the chamber trough wireless communicators wich can be recharged using a dynamo. No organic material other than SCP-AAAA-A should ever come into contact with SCP-AAAA.
In case of a containment breach hydrochloric acid is sprayed into the chamber and all effected organisms are terminated after 2 days of quarantine and interrogation to prevent any type of spreading of SCP-AAAA-1. All instances of SCP-AAAA-1 outside containment area are to be incinerated, reducing the chances of containment breach.
All testing requires the permission of one of the D-0-A research group's researchers.
Description: SCP-AAAA is a Red morning glory plant (Ipomoea coccinea) tangled around a grey cattle's skull. The skull is covered in SCP-AAAA-1 and has a faint golden glow.
Anything coming into physical contact with SCP-AAAA or SCP-AAAA-1 is considered infected, all infected organic matter (with the exception of animals from the family Bovidae) gradually turns into SCP-AAAA-1 in 44 hours on average.
SCP-AAAA-1 can be any type of moss, and it doesn't seem to be affected by the assimilated tissue.
SCP-AAAA acts as the reproductive organ of SCP-AAAA-1, it spreads using spores and pollens, wich are produced by all parts of SCP-AAAA. All organic materials that come into contact with these spores gains a very strong regenerative property that seems to prevent its death, or any reduction in its mass. Testing showed that an adult human 4 hours after infection, was capable of regrowing severed limbs in a matter of minutes, and had an incredible boost in stamina. Infected animals lose their apetite completely, after being exposed to SCP-AAAA, however, this seems to be the opposite after being exposed to SCP-AAAA-1, gaining an immense desire to overfeed.
Organic matter starts to turn into SCP-AAAA-1 two hours after contact, 48 hours after contact a human being is competely turned into SCP-AAAA-1. Testing showed that human beings who were in the late stages of assimilation by SCP-AAAA-1 (over 24 hours) and has eaten from SCP-AAAA out of desperation, had their assimilation completely stopped, but not reverted.
However due to the body of all SCP-AAAA-A instances being mostly made of SCP-AAAA-1 they have to be contained in the same way SCP-AAAA is.
SCP-AAAA-A's doesnt require any substance to keep themselves functioning for a period of ██ weeks.
Addendum: Testing showed that after complete assimilation, tissue that became SCP-AAAA-1 loses its regenerative properties completely, however SCP-AAAA-A as an unfinished assimilation, retains it.
Item #: SCP-BBBB
Object Class: Safe
Special Containment Procedures: SCP-BBBB is allowed to roam around the entirity
of the D-0-SD facility due to its nature. SCP-BBBB is fed 2 times a day with ██████ brand dog food, personnel aren't allowed to feed SCP-BBBB more than 1,3kg a day. Upon containment breach personnel are to search for the exit it made. In this event available personnel should try call it back by whistling and carrying dog treats to lure it back into containment.
Description: SCP-BBBB is a male crossbred dog (50% Pit Bull 25% German Shepherd 25% Dachshund) weighing around 11Kg and was discovered when the entrance of the D-0-SD facility was breached by it, leaving a 40-50 cm hole in all 6 layers of reinforced steel containment gates.
Surveilance cameras recorded the dog running through the gates, using its backside legs in a hopping manner. All attempts to restrain SCP-BBBB will inevitably fail, as one of its anomalous properties is that its movements cannot be stopped, unless it wants it, this means that not even its cells can be moved or harmed in any way. Its sense of smell and hearing is capable of recognizing humans from a distance of over 3 kilometers. Attempts to restrain SCP-BBBB ends up with it either phasing through objects or beings, seemingly teleporting, or SCP-BBBB simply moving the way it wants to, applying (seemingly endless) force, currently witnessed feats that prove them: (See Incident log BBBB-1 and BBBB-2.)
Addendum:
Item #: SCP-CCCC
Object Class: Safe
Special Containment Procedures: SCP-CCCC is kept in a steel cage fitting its size, it is located in an isolated concrete room at site D-0-██.
Description: SCP-CCCC is a mechanical clock mechanism, made out of obsidian and gold, its size is 0,3x03,x0,5m and weighs 6 kilograms, it doesnt require electricity or rewinding.
It has 2 holes in it, wich are speculated to be where it can be connected to an unkown machine.
SCP-CCCC has the ability to stop time outside of a 12m spherical zone, centered around SCP-CCCC. This effect happens whenever SCP-CCCC's hands are at the same spot. This effect lasts until 1 minute inside the uneffected area passes. Until the effect of SCP-CCCC is active, leaving the uneffected area will cause any organic matter to instantly vaporize.(with the exception of calcium based compounds).

Item #: SCP-DDDD
Object Class: Safe
Special Containment Procedures: SCP-DDDD is kept in a standard humanoid cell
at site D-0-██. Personnel with clearance level 2 or above may enter SCP-DDDD's cell and interact with it, for testing purposes. It is not advised to use any device capable of recording visual information to capture footage of SCP-DDDD.
Description: SCP-DDDD is a dark stone sphere with a diameter of 14,6cm. The sphere cannot be moved from its place, unless a human being with an IQ of less than 85, has a clear view of it. Any and all attempts to move the object while it is in its immobile state resulted with a failure.
Individuals who meet the requirement reported seeing a tall (approximetly 190cm) humanoid shadow (reffered to as SCP-DDDD-A), sitting where SCP-DDDD is supposed to be. Visual recordings of SCP-DDDD are heavily modified or distorted, to an extent where the original entities are barely recognizable (Reference document Addendum 2).
SCP-DDDD-A is capable of understanding human speech, and knows ██ different languages, it is theorized that it uses vibrations in the air to produce sounds that replicate speech. SCP-DDDD-A doesnt seem to be aware of the existance of SCP-DDDD, and also does not refer to humans using their names, but their titles and a distorted low pitched sound. (Note: SCP-DDDD-A uses fictional, and abstract titles without previous knowledge about them, as long as the one who bears the title recognizes it as fitting.) (See interview log 1) SCP-DDDD has knowledge about mythical and religious beings, items, and stories, as if they were real.

Interviewed: SCP-DDDD
Interviewer: Dr. Molnar Roland
Foreword: The interview is aimed to question of SCP-DDDD about its origins, intentions, and capabilities.
<Begin Log, [1995. ██.██. ]>
Dr. Molnar Welcome DDDD, Im Dr. Molnar Roland. Im here to ask you a few questions.
SCP-DDDD Hello Dr. [Inaudiable] its nice to finally have someone talk to me who doesn't breathe through their mouths. You know, ever since i've been your guest, All the company i got, was your guards and these pesky idiots, who cant even comprehend 3 sentences in a row…

SCP-DDDD Alright… So the

Item #: SCP-EEEE
Object Class: Safe/Euclid/Keter (indicate which class)
Special Containment Procedures: [Paragraphs explaining the procedures]
Description: SCP-EEEE is a male humanoid, its original form being approximetly 195Cm tall, wearing a brown hood, that casts a shadow over its face even when light is directly shining on it, that makes observing its face accurately, impossible. SCP-EEEE is observed to be able to change its appearance and physical traits seemingly without any limitation. It can use this ability on anything in the world. Currently most researchers in the D-0-SD facility refer to this anomalous ability as "Reality warping". SCP-EEEE demonstrated that using SCP-CCCC he can manipulate time inside SCP-CCCC's area of effect. (For complete report, see incident report: EEEE-1
