Eheheheheh! This was fun!

The voice of the Ravenclaw prefect did nothing to stop them from pulling at the Slytherin's hair. It only provoked them more. Little blue tongues stuck out at her, pixie spit leaving their mouths. They didn't take orders from stupid humans. And then that other girl was screaming now. One of the duo zoomed off toward her, circling around her and kicking at her head.

But the other pixie was still following after its target. You could run, but not forever. Your pesky pixie pal was there to stay. Hehehehe!
