Write an additional entry for this hypothetical SCP document: "Item #: SCP-XXX
Object Class: Safe
Special Containment Procedures: All instances of SCP-XXX are to be contained within a specifically-constructed humanoid containment cell at Site-██, expanded to 25m x 25m x 25m to account for the number of instances, and to accommodate the size of SCP-XXX's breasts. The cell is to be fitted with a padded floor and walls to accommodate the size of SCP-XXX's breasts and to minimize the risk of damage to infrastructure in case of accidental collisions. Currently, none of the twenty-two instances have shown any signs of needing to eat, sleep, or otherwise engage in recreational activities since their containment on 200█/██/██, and as such no additional necessities need to be provided as of this writing.
Description: SCP-XXX, collectively referred to as the "Bonita Zako", is a collective group of twenty-two (22), perfectly identical humanoid women, each approximately 1.33 meters (~4'4") in height and weighing approximately 34.08 kilograms (~75.13 pounds), with the exception of its 'breasts', which have been estimated to weigh approximately 2 tonnes per instance. Their appearance can best be described as cartoonish and simplistic, with digitless nubs for feet and hands, simple faces with small circles for eyes and a 'cat smile' (it is to be noted their facial features do not have any 'depth' to them, as if they were painted onto their faces, and so far none have once deviated from this expression since the day of their discovery and subsequent containment), and blonde hair tied into a twin-tails fashion. Their most noticeable and intriguing feature, and the main reason for their containment, is the presence of two giant, perfectly globular orbs affixed to its chest, acting as its 'breasts', though it's currently unknown if these are its actual mammaries or extraneous extremities that simply resemble such in shape, each measuring approximately 1.9 metres (6.23 ft) in diameter and 3.53 cubic metres (124.66 ft³) in volume, and has thus far not deviated from an anomalous density of 134.22 kg/m³ (8.37 lbs/ft³). Each 'breast' weighs approximately one tonne resulting from this unusual density, yet all instances of SCP-XXX are able to effortlessly carry this weight without any difficulty or visible stress upon their body. It is currently unknown how the instances of SCP-XXX are able to do this, as they do not outwardly exhibit any physical abnormalities or strength beyond what would be expected of a humanoid of its size. The exterior of each instance is composed of a material that is anomalously identical to the outward appearance, elasticity and texture of smooth latex rubber, similar to that of a regular party balloon's, either peach or tan in colour, though any attempts to cut, misshape, or puncture the surface of any instance of SCP-XXX's body have so far all been met with failure, as the anomalous material simply bounced back and retained its original shape. Every instance unanimously wears what appears to be an anomalously elastic single-piece swimsuit, either blue, red or black in color, and do not seem to be removable nor damageable via any means, as if it were a natural part of its body, and any instance has thus far not been seen without wearing such. Each instance does not seem to possess any sort of higher intelligence, self-awareness or separate personality, and have so far only reacted with mild curiosity to both physical and visual stimuli, including the aforementioned attempts to penetrate its surface, though they have been observed to be drawn towards excessive movement and will crowd around any person that is unlike them. None of SCP-XXX's instances seem to be capable of creating nor holding verbal communication of any capacity; however, when in close proximity to other instances of SCP-XXX, individual entities have been observed to occasionally vocalize a series of anomalously produced noises which have been likened to high-pitched giggling similar to that of a female child's, which appear to be a form of non-verbal communication, though translation of this dialect has been deemed impossible.
The entities were first brought to the Foundation's attention in the █████████ area of New York City in 200█, where they were sighted by locals and imbedded Foundation personnel during a routinely patrol of the area as they wandered aimlessly through the streets, with the majority of instances remaining inert when approached or prodded. Witnesses of the entities described them as "bouncing babes with giant breasts", though none who had witnessed them found them to be unusual in any way, despite being fully aware of their strange appearance. All ██ witnesses were given Class A amnestics. When further Foundation presence arrived on the scene, they found twenty instances of SCP-XXX wandering about within the town square; two more were found nearby and contained after they were discovered having gotten stuck inside a revolving door leading into the ██████ █████ Bank, presumably because the two instances had attempted to enter the building simultaneously. Prior to containment, it was determined that the instances did not possess any sort of spatial knowledge, and were simply wandering aimlessly with no apparent purpose or destination. How they had appeared in such a populated area with nobody noticing beforehand, and how they came to be, is currently unknown.
Addendum SCP-XXX-A: A possible explanation for the instances' apparent obliviousness to its immediate forward surroundings is its inability to see past its large 'breasts', rather than any lack of vision or an anomalous property pertaining to it, though this does not explain its preference to remain stationary."
