Per 
SCP-3561 on it's sheet of paper.
Item #: SCP-3561
Object Class: Euclid-Safe
Special Containment Procedures: SCP-3561 is to be kept on a 7" x 16" piece of sketching paper. The paper is to be kept in Dr. Garner's pocket. SCP-3561 is to be let out at least once a week to be fed and socialized, with only Dr. Garner allowed to speak to it unless Dr. Garner gives permission to other personnel. If the requirements are not met, SCP-3561 will come off the paper it's self to fulfill its needs, in which MTF █████-█, who don't suffer from Ophidiophobia, are to watch the exits out of the site which ever site Dr. Garner is at.
Description: SCP-3561 is a serpent resembling a constrictor build with venomous fangs, with red diamonds on it's length. SCP-3561 measures about 1 foot 4 inches on paper but outside the paper it can take any size it wants, with it's largest measurement being the length of 30 US standard school buses. As Mentioned SCP-3561 has venomous fangs that produce a slow effecting neurotoxin of unknown identity, but it can produce a "anti-venom" of sorts which is the only means of curing it other than SCP-███. Tests on the "anti-venom" show it can cure subjects of its poison but when used on Dr. Garner it can heal wounds and cure diseases such as the common cold. The effects of this is unknown. What is known is that Dr. Garner had somehow created SCP-3561. The ways and how he did this is still unknown. SCP-3561 is able to speak vocally to all staff. D-Class who speak to SCP-3561 who have Ophidiophobia, the fear of snakes and serpent-like creatures, will freeze as if turned to stone with faces of fear. They will be like this until SCP-3561's "anti-venom" is administered or they have been terminated.
Addendum:The Following is an Interview with SCP-3561 on the subject of who Dr. Garner was. This was recorded on tape:
Interviewed: SCP-3561
Interviewer: Dr. ████
Foreword: The Interview was in a Foundation protected park as requested by SCP-3561. Dr. Garner has agreed to leave to the other side of the park as the interview happened. Dr. ████ was using a tape recorder and notepad to correct logs in case.
<Begin Log, █/██/████ 10:03 AM>
Dr. ████: "We want to know… Who is Dr. Garner and how did he create you? The Foundation bares very little information on him which is very ███████ peculiar."
SCP-3561: (Seems to chuckle) "Language my good researcher… Such dirty words from a pretty mouth. Anyway… I'm genetically unable to tell you how I was made, or who Dr. Garner is. Such a glorious person he is. The Hair, the walk, the…" (SCP-3561 is cut off by Dr. ████)
Dr. ████: "If by glorious you mean a 16 year old virgin who looks depressed all the time…"
SCP-3561: (Hisses at Dr. ████ with hostile emotion on its face) "You can shut your gob… He's only depressed like that because of what you say about him… bullying is a thing doctor…"
<End Log>
Closing Statement: Recording was cut due to SCP-3561's hostility. Dr. ████ was escorted away to a safe distance. SCP-3561 slithered away at a measurement of 8 feet back to Dr. Garner, whom SCP-3561 attempts to comfort. Further questioning is now only allowed to proceed if the Following Doctor or D-Class here by agrees to not to downgrade or dismay any complements said by SCP-3561.
