It's a pun. "Kyuuri no Kitsune" (Cucumber Fox) instead of "Kyuubi no Kitsune" (Nine-tailed Fox)

Nice play on words. I kinda expected 9 cucumbers at once, but I thought it'd be painful..

I think Nitori ate the other eight.

should it go into the Clever pool?

Oh, I'm kinda blind. From the color scheme and hat, I thought it was another Suwako-hat-joke picture when I saw the thumbnail. Did NOT see the cucumber at all.
