There were a few perks to having no house elves other than Toddles. One was the obvious - ice cream ALL THE TIME at every meal. And it was such GOOD ice cream, too, and now Mo was thinking about stopping in the kitchen on his way back to Potions, which was just a terrible idea. He was already out of time.

The OTHER perk was that there were corners of the castle that were getting very VERY dirty, one of which, Mo assumed, might be this closet. Not that it was good that things were getting dirty, but Mo needed a little filthiness to complete this last task. After entering the closet, he shoved over the buckets and mops and things and searched the corners.

Surely SURELY if there was anywhere in the castle that... ah, there it was. Mo gulped a bit as he reached out and grabbed the cockroach from behind the bucket. It looked at him and the little legs flailed and Mo felt a bit sick. He dropped the thing into the bag in his satchel and continued his search for more cockroaches. Ugh.
