Sorry, not to be annoying, but "than not get her at all" isn't much of an argument. There's no reason why they wouldn't make Octavia because of the tentacle issue. Clearly, they are making her, and taking the easy route of doing stiff tentacles.

If they'd never revealed Octavia and had no plans to make her because "we wouldn't want to make her unless the figure had bendy tentacles, because that's the way she should be", that would be another story.
