No, just the sound of something rickety wiggling around. It's the same SFX usually used when someone's wiggling their fingers in anticipation of grabbing something (such as treasure, or breasts but I repeat myself); in this case, it's being used as the SFX for the kappa arm teetering about.
Ibara is not the kind of person to survive for long in Gensokyo. At least not when near a sunflowerfield or the yakumos.
That was you, wasn't it?wiggle wigglerickety-soundingThat?The ends of their lives?That's right.If only there were a way for humans to live longer...Idiot!That reminds me! I was just thinking about the naggy little hermit we used to get around these parts.Ack!That is because I cannot contain my indignation toward today's degenerate youth.If things continue as they are, humans will lose their ability to survive.Unable to defeat the shingami, they will meet the ends of their lives.And even the power to defeat youkai will...Actually, I suppose that's what hermitry is.
