And are looking a bit pasty, to be honest. To the Japanese, they are known as 'ningen'. They are giant, white skinned humanoid creatures that lurk 'neath polar seas, and occassionally hop onto the ice for a toddle around. It's all at the excellent Pink Tentacle blog.
Reportedly observed on multiple occasions by crew members of government-operated “whale research” ships, these so-called “Ningen” (lit. “humans”) are said to be completely white in color with an estimated length of 20 to 30 meters. Eyewitnesses describe them as having a human-like shape, often with legs, arms, and even five-fingered hands. Sometimes they are described as having fins or a large mermaid-like tail instead of legs. The only visible facial features are the eyes and mouth.
An non-urban legend wouldn't be the same without some of that good ol' grainy footage. So here's some.
Oo-er fertang, or however you say it. I'm convinced. I'm never going near the polar regions again. And I want my teddy.
