When the Octocat Mark is rendered at any size less than 75x75 pixels, it's pretty much impossible to tell that the "tail" of the cat is actually a tentacle.
That's unfortunate, because on https://github.com/logos the only recommended use for the mark is in social buttons, which are going to be relatively small.
Even at larger sizes, the tentacle just seems tacked on.
See the home button in the upper left corner of the page. You don't see the suckers but it is recognizable. I don't think they're terribly worried about seeing those details.
Agree. They should have a guideline about using the cat at small sizes, or provide customized low-rez versions. I looked at it and thought it might have worked better if they ditched the suckers and just used multiple waving tentacles.
