Ribbon stood up on tip-toes, cupped her hands around Helena's ear, brought her mouth close to whisper in it, then pinched her on the earlobe and put her out. For the most part the way Ribbon's power worked was that when she made contact with a particular body-part she could put that body-part to sleep, but when she touched the head - or near enough to it - she could put the brain to sleep, and when that went everything else tended to follow.
Ribbon caught Helena as she went down and guided her to the ground as gently as she could. She then positioned her feet so that she was standing over her, lifted the skirts of her dress up and crouched so that her rear was approximately above Helena's face.
Ribbon may not do a very good job of it, but she really tried her best to act like a young lady, and so she'd been holding this in for a very long time. Smirking in an ever-so-satisfied manner, Ribbon let loose with a rather long, rather loud and wholly disgusting fart. Her work done, Ribbon straightened up again and placed a hand gently on Helena's forehead, waking her up again.
"Hey, listen. I don't think we should fight. You and me could be real good friends, we don't have to be mean to each other." Ribbon smiled broadly and reached a hand out to help Helena up to her feet. "I'm Ribbon. I don't mind anything you said to me any more, it hurt my feelings but it's all water under the bridge now. Let's be nice to each other from now on."
