ibanny tail!!!! to me its like an ahoge but in the ass, wiggling depending on his mood, and with extreme high frequency around tillbun. if you cant guess ibanny's feelings based on the curve of the smile, then look at his butt! i like to think about the noises he would make if the scut is pulled, or maybe it works like a switch that shuts him down and left him flopping onto the floor- either way ibanny tail is one amazing creation
