You see them in anime. You see them in manga. And yes, you see them in video games. Octopus tentacles are, and have been for centuries, common tropes.
One Japanese fisherman, however, uses something quite unusual.
"Ah, yes, tentacle play," wrote one commenter on bulletin board 2ch. "I see."
Others were completely bewildered, wondering the hell was going one, while some called this a "yarase" or "faked situation". Sometimes things on Japanese TV are apparently phony. Other times, they are horrifyingly real.
The fisherman's rationale is that red shapes fool the octopus into thinking they're crabs—hence all the red colored figures.
The clip originally appeared on Japanese morning TV show, Zip. I was once interviewed for Japanese morning television—this same network—and that was real. Then again, I wasn't talking about catching seafood with anime figurines.
