Description: SCP-098 is a species of previously unknown crustacean. They resemble crabs, but rather than chelae, the front limbs terminate in knife-like structures that incorporate silica to form an extremely sharp edge. Specimens reach larger size than normal for land-dwelling arthropods, at 40 centimeters tall and as large as 60 centimeters across.

Description: Moved to Site-19 1993. Origin is as of yet unknown. It is constructed from concrete and rebar with traces of Krylon brand spray paint. SCP-173 is animate and extremely hostile. The object cannot move while within a direct line of sight. Line of sight must not be broken at any time with SCP-173. Personnel assigned to enter container are instructed to alert one another before blinking. Object is reported to attack by snapping the neck at the base of the skull, or by strangulation

Description: SCP-049 is a humanoid entity, roughly 1.9 meters in height, which bears the appearance of a medieval plague doctor. While SCP-049 appears to be wearing the thick robes and the ceramic mask indicative of that profession, the garments instead seem to have grown out of SCP-049's body over time1, and are now nearly indistinguishable from whatever form is beneath them. X-rays indicate that despite this, SCP-049 does have a humanoid skeletal structure beneath its outer layer.

Description: SCP-939 are endothermic, pack-based predators which display atrophy of various systems similar to troglobitic organisms. The skins of SCP-939 are highly permeable to moisture and translucent red, owing to a compound chemically similar to hemoglobin. SCP-939 average 2.2 meters tall standing upright and weigh an average of 250 kg, though weight is highly variable. Each of their four limbs end in three-fingered claws with a fourth, opposable digit, and are covered in setae which considerably augment climbing ability. Their heads are elongated, devoid of even vestigial eyes or eye sockets, and contain no brain casing.

Description: SCP-682 is a large, vaguely reptile-like creature of unknown origin. It appears to be extremely intelligent, and was observed to engage in complex communication with SCP-079 during their limited time of exposure. SCP-682 appears to have a hatred of all life, which has been expressed in several interviews during containment.

Description: SCP-407 is a song in an unidentified language, seemingly sung a cappella. The voices are thought to be human. The tape containing SCP-407 was found with one track of approximately thirty (30) minutes duration, though the abrupt ending suggests there may be more. The song has been described by all listeners as something along the lines of 'soothing', 'glorious', and 'beautiful'.

Description: SCP-066 is an amorphous mass of braided yarn and ribbon weighing approximately one kilogram. Strands of SCP-066 may be taken individually and manipulated; when this is done, a note on the diatonic scale (C-D-E-F-G-A-B) is produced by the object.

Description: SCP-035 appears to be a white porcelain comedy mask, although, at times, it will change to tragedy. In these events, all existing visual records, such as photographs, video footage, even illustrations, of SCP-035 automatically change to reflect its new appearance.

Description: SCP-058 resembles a bovine heart, with four (4) arthropod-like legs used primarily for movement, and four (4) tentacles of adjustable length, covered with razor sharp spines. It has a single sharp 'stinger' on its rear, where the hole for the superior vena cava would be in a typical organ. SCP-058's tentacles can be "whipped" to a distance of 3.2 m (10.5 ft) at speeds in excess of 320 km/h (200 mph). SCP-058 is extremely hostile and will use every opportunity afforded to it to inflict damage on its surroundings.

Description: SCP-811 is shaped similarly to a human female with disproportionally long and thin limbs and a slightly-bloated abdominal region. It is 171 cm tall, and weighs just under 47 kg due to its strange physiology (see Addendum 811-2 for details). Its skin has slight abrasive properties, and is a mottled green color that serves to camouflage it among the reeds in its natural habitat. Its sweat has been observed to act as a mild skin irritant. It has extremely oily black hair that has proven to be resistant to cleaning with conventional shampoos (See Addendum 811-1). It shows partial comprehension of human language, consistent with case studies of "feral children" that had been abandoned at a few years old, instead of as infants.

Description: SCP-999 appears to be a large, amorphous, gelatinous mass of translucent orange slime, weighing about 54 kg (120 lbs) with a consistency similar to that of peanut butter. Subject’s size and shape is easily malleable and can change shape at will, though when at rest, SCP-999 becomes a rounded, oblate dome roughly 2 meters wide and 1 meter in height. The surface of SCP-999 consists of a thin, transparent membrane similar to that of an animal cell roughly .5 cm thick, and is highly elastic, allowing SCP-999 to flatten portions of its body up to 2 cm thin. This surface is also hydrophobic, although SCP-999 can willfully absorb liquids (see Addendum SCP-999-A). The rest of SCP-999's body is filled with a viscous orange substance of unknown chemical makeup, though it is capable of digesting organic materials with ease.

Description: SCP-1176 is the mummified corpse of a human male, presumed to have been approximately 35 years of age at the time of death. Severe tissue degradation has made DNA examination of SCP-1176 impossible; based on contextual evidence, SCP-1176 is assumed to have been of Arabian ancestry and to have died in the 10th-11th century AD. SCP-1176 is clinically dead and does not display any indications of respiration, circulation, or metabolism. SCP-1176's brain, which is largely intact in spite of general tissue degradation, exhibits a constant level of electrical activity consistent with stage 3 non-rapid eye movement sleep ("deep sleep").

Description: SCP-993 is a children's television program entitled "Bobble the Clown" which first began airing in ██/██/19██. SCP-993 seems to have been made in the style of an educational cartoon, with the primary plot of most episodes being the titular character, Bobble the Clown, learning a new skill or activity. The program appears to have no supporting cast and the setting of the program often changes between episodes.

Description: SCP-1026 appears as a black humanoid figure with no distinguishable age or gender. SCP-1026's height is measured at 191 cm, weight ranges from 30 to 70 kg. Facial features are extremely hypertrophied: its eyes are red and oval shaped, whilst emitting a slight glow. SCP-1026's mouth is a wide white smile that shifts size whilst talking. SCP-1026 does not have a distinguishable nose, nor distinguishable ears and hair. SCP-1026 is able to change its shape in a limited way depending on the mood, situation or need. The majority of its body can be subject to such transformations.

Description: SCP-1507 is the collective designation given to thirty plastic lawn flamingos of unknown make or manufacturer. Instances of SCP-1507 bear no notable behavioral differences from the average American Flamingo, save for an increase in territorial behavior and lack of vocalization. Said behavior often results in attacks targeted towards Foundation staff. The only individual known to circumvent their behaviors is PoI-1507, otherwise known as Leroy Day. Hume level testing performed on PoI-1507 suggest reality bending abilities, though all conversations with him have come back as unclear of his awareness of his abilities.

Description: SCP-689 appears to be a small green soapstone statue, 30 cm in height. It is carved in the semblance of what appears to be an unknown deity of the underworld, a seated skeletal figure with hands clasped over knees. It was discovered by ███████ ██████████████ during one of the prewar German archaeological expeditions in the ████████ area of India and obtained after the war by the OSS. Its location during the war is unknown. SCP-689 is completely inert for as long as it is being watched by at least one human being. Normal behaviors such as blinking do not appear to interrupt the "watching" for this purpose, but any lapse in attention, however momentary, renders the observer vulnerable. As soon as SCP-689 is unobserved it vanishes from its current location.

Description: SCP-1057 is an animate empty space, five (5) meters long, in the shape of an adult tiger shark (Galeocerdo cuvier). It does not appear to have any mass; however, it displaces water by an unknown mechanism. SCP-1057's refractive index is approximately that of air, which makes it partially visible when immersed in salt water; as well, its "anti-shadow" is discernible under bright light. Experiments involving the insertion of inanimate objects into SCP-1057's "body" have revealed that there is nothing there; however, further experiments along these lines are contraindicated, as this triggers extremely aggressive behavior on the part of SCP-1057.

Description: SCP-023 is a large, sexless shaggy canine (1.5 meters at the shoulder) with black fur. It has bright orange-red eyes and prominent teeth. Any time an individual makes eye contact with SCP-023, either that person or a member of their immediate family will die exactly one (1) year after eye contact is broken. Research into the method of selection is incomplete due to a moratorium on experiments, but the available data suggests that having a larger immediate family lessens the chance of the individual making eye contact themselves dying, and neither a pattern nor a preference in victim types have been found. This may indicate that SCP-023's victim is designated entirely at random, but it is unknown whether this selection occurs at the beginning or at the end of the one-year time period. Attempts to terminate an individual who has made eye contact with SCP-023 and their entire immediate family before the one-year time period has ended [DATA EXPUNGED].

Description: SCP-650 is a black statue of a stylized humanoid 167cm tall. The statue does not possess hands or facial features: the limbs taper off into rounded points and the head is a smooth surface all around. The default posture while under observation has the statue reaching upwards, head tilted as if facing the sky. Composition of the statue is currently undetermined; materials testing has yielded inconclusive and contradictory results.

Description: SCP-1762-1 is a plain, cardboard box that is 32 cm x 20 cm x 26 cm. It is spray-painted silver on the interior and exterior, and the words "HERE BE DRAGONS" are handwritten in black permanent marker on the lid of the container. Opening the lid of SCP-1762-1 when it is not in the process of a release reveals it to be empty. SCP-1762-1 will infrequently open and initiate a release of SCP-1762-2. During this time, the box will briefly emit a large amount of black smoke that quickly dissipates; it takes an average of twenty seconds for SCP-1762-2 to emerge after the smoke clears.
