Not sure I'd say I have a fetish for tentacles, but they are interesting! I'd buy it, just for the curiosity factor. Plus, it seems like one of those toys you could leave out and just say "I like octopi so I bought a squishy desk ornament" if you've got privacy issues. Just make sure you clean it well before and after!
And silicone is usually really soft and squishy, so the curve is no problem.
