Special Containment Procedures (revision 6): New SCP-5133 instances should be sterilized using Beta class radiation directed at their reproductive organs (relative to their closest non-anomalous species) for approximately five minutes for two months, unless there are designated SCP-5133-1 instances.
SCP-5133-1 instances are to be kept in a 7 by 7 meter containment room, with a height of at least 4 meters and be filled with half a meter of dirt with a grass layer for SCP-5133's "burrowing" habits. The walls of the containment room should be fitted with experimental magnetic field emitters (MFE-7) to prevent discourage1 SCP-5133 instances from escaping. If less than three SCP-5133-1 instances are in containment, the next discovered SCP-5133 instance is to be designated SCP-5133-1 and is not to follow sterilization protocols.
SCP-5133-2 instances are to be kept in a 15 by 15 by 4 meter containment room with the same specifications as mentioned for SCP-5133-1. The containment chambers for SCP-5133-1 and SCP-5133-2 are to be at least fifty meters apart to avoid intermixing.
If containment failure is to occur, personnel are to remain in large rooms and/or open spaces2 if possible. SCP-5133 instances can be recontained by using food to lure them if they are scheduled to be fed soon. If this is not possible, instances can also be recontained by the use of strong magnetic fields, but this will usually aggravate the entities further.
An SCP-5133 instance.
Description: SCP-5133 refers to an incorporeal subspecies of European Rabbit (Oryctolagus cuniculus). All SCP-5133 instances appear exactly identical, being roughly 40 centimeters in length, 20 centimeters wide, and 10 centimeters tall. Instances are translucent and have a variety of constantly changing colors described by researchers as "translucent rainbow ghosts." Due to the nature of SCP-5133 instances, only two classifications have been given despite SCP-5133 having nine known instances.
Instances' normal behavior includes "jumping"3, "swimming"4, and "burrowing"5. Additionally, SCP-5133 is not a territorial species. They do not respond to any other animal or entity (including human subjects) entering their containment chamber. When a new SCP-5133 instance is introduced into their population, they are quick to accept the new member.
All SCP-5133 instances require feeding roughly every 46 days. SCP-5133 instances consume a unique type of radiation designated 5133-A emitted by a special plants that grow in their natural habitat. 5133-A type radiation is mildly dangerous to humans and can produce side effects such as loss of sight under long-term exposure.
SCP-5133-1 are the natural form of SCP-5133 and can reproduce given specific conditions (such as having enough food and being "willing"). SCP-5133-2 are a limited form of SCP-5133 by design of the Foundation. They are made unable to reproduce by use of Beta radiation to prevent an uncontrollable number of SCP-5133 instances to be created. Three SCP-5133-1 instances are kept for research into their reproductive cycles and behaviors. Personnel must monitor the food consumption of SCP-5133-1 instances to prevent unintended creation of new instances.
When aggravated, the SCP-5133 instances will group together and use their nonmaterial ability to pass through their aggressor. Shortly after they begin their attack, the inflicted person will expire from organ failure. Currently, there is no known way to treat this. SCP-5133 instances will also be more likely to pass through the walls of their containment chamber and may unexpectedly appear and attack in neighboring corridors. It is worth noting that SCP-5133 instances do sometimes pass their containment barrier when not aggravated.
It is also worth noting that SCP-5133 instances can choose to attack when moving through a subject, human or nonhuman. On several occasions an instance has gone through personnel and not damaged them in any way. Personnel recall felling "a tingling feeling" in the location where the entity passed through.
SCP-5133-1 are appear genderless but require two of the same species in close proximity to propagate. Instances breed when they have a sufficient amount of food, approximately 450 rads, and will proceed to dance around each other. After breeding, both of SCP-5133-1 instances that bred will be impregnated. One month after becoming impregnated, an SCP-XXX-1 instance will give birth. Birth of a new SCP-5133 instance cannot be observed by the human eye or any observational device. A notable example is when playing back recording devices, footage is of normal activities until the pregnant SCP-5133-1 instance leaves the videograph capture radius. Only then will the instance return with the child. While someone is physically inside the the containment chamber, pregnant SCP-5133-1 instances will only give birth when eye contact is broken (including blinking).

Jan 9, ████ - SCP-5133-2 instance kills two personnel. Switching from current nonmaterial technology to magnetic containment technology.
Jan 13, ████ - An SCP-5133-1 instance escapes containment and kills ██ security personnel. Looking into other nonmaterial containment alternatives.
Jan 19, ████ - An SCP-5133-2 instance kills personnel during feeding session. Submitted request to use new suppressive technology. Request denied Jan 20, ████.
Jan 23, ████ - Head researcher personally comes to inspect containment chamber. Allows use of experimental magnetic containment technology. Construction finishes Jan, 29 ████.
Feb 3, ████ - SCP-5133-2 instance escapes containment and kills two maintenance personnel.
No conclusion on containment procedures.
Addendum: 5133.2 - Doctor Richman's Proposal (Synopsis)
Due to the nature of SCP-5133 and the difficulty of its containment, SCP-5133 should be moved to a provisional site, preferably a location with only one traversable area and far away from any landmass (such as the under-construction Site-114 in the middle of the ███████ ocean). Moving the SCP-5133-1 instances to an isolated location as an experiment could prove useful in learning how to contain all SCP-5133. This may also decrease the amount of unintended fatalities that occur.
