Because Patchoulis weren't moe enough, they needed extra meganekko sperks to crank up the cute...
Hmm, kinda on topic, but, I'm the onlye one who, while seeing patchoulies, can't help but see it like if it were lying like a dog?
I mean, because of the braids/flaps being like arms for yu's and patchouli having 2 in front of her all the time, it kinda makes her look like doing the same position dogs do while lying on the floor.
