Absolute Johannes factotum
- SCP-6105 (?)
- SCP-6105 is an unusual iceberg in the Antarctic ocean that floats entirely on the surface and is 225 meters tall and 376 meters wide. It can only be seen and touched by humans and the ocean itself; other objects and animals pass right through it, and cameras cannot record it. The iceberg is indestructible, has not changed since 1832, and has a message carved into its north face that reads, "ONLY HUMANS CAN SEE THIS." To prevent people from accidentally seeing it, a 15-kilometer exclusion zone is maintained around it by patrol vessels.
- Pittsburgh refrigerator cat (?)
- The "Pittsburgh refrigerator cat" was a widely circulated, spurious breed of cat in the late 19th and early 20th centuries, initially reported by newspapers in 1894. These cats were supposedly thick-furred, short-tailed, and cold-loving, having evolved in Pittsburgh's cold storage warehouses to hunt cold-adapted rats, and were believed to suffer heat exhaustion at normal temperatures. Although a respected naturalist, Richard Lydekker, initially lent credibility to the story, it was debunked by 1895, revealing that a cat had simply given birth to a litter of pink-eyed albino kittens in a cold room, which subsequently grew thicker fur due to the environment rather than natural selection.
