And so he made his bottom dirty by plopping down onto the muddy banks of the black lake. Cutty stared out onto the glassy surface, which was only disturbed by a ripple here or there, and considered his plan carefully. He'd spent a portion of his summer researching the gone-by Tri-wizard tournaments Professor Dursley had mentioned. It gave him foul little ideas.

The last time he'd been out on the lake, Cutty had been transfigured, his nose being that of an animal's. The effects of which he'd found to be quite remarkable for it gave him an enhanced sense of smell and felt to him like having an extra set of eyes. He noticed things like where certain creatures lived and the different types of vegetation that could be found out on the grounds. There were also things in the Forbidden Forrest that carried a smell unlike any other, but the effects of Bronislava's magic had worn down too much by the time he'd reached the borders.

Cutty got into the water clothes 'n all, leaving behind only the vague imprint of his buttocks on the soft mud of the bank and perhaps a footprint or two. He had business to attend to and his fellow Slytherins would soon find out what it was.
