[SCP-7182 manifests as a small-sized dolphin characterized by a black and white coloration. Notably, SCP-7182 secretes a purple substance from its blowhole, designated SCP-7182-1. Contact with SCP-7182-1 triggers a phenomenon wherein additional instances of SCP-7182 are generated upon contact with living organisms. This reproductive process is primarily activated during SCP-7182's feeding periods, particularly when consuming goldfish, which serves as the most potent trigger.
Of note, they have a sandbox, which appears to have the raw (pre-AI) text of one of the coldposts: https://scp-sandbox-3.wikidot.com/scp-7180
Description: [SCP-7182 is an black and white dolphin that is somewhat small. The purple substance that comes out its blowhole is known as SCP-7182-1. If it is to touch a living object more SCP-7182's will be made. A SCP-7182 can only do this deadly action when eating. The goldfish is the one that triggers it the most. An SCP-7182 can only do this 30 times, after that SCP-7182 dies. The person that is infected by SCP-7182-1 is now considered SCP-7182-2. Once SCP-7182-2 is infected after a couple of days, SCP-7182-2 will feel extreme stomach pains. After one month the pains will go away. But SCP-7182 will feel the urge to go to the ocean. Once there, SCP-7182-2 will vomit out he's/she's organs and a baby SCP 7182 will come out.]
