Walter wheeled the grindylow tank into the pool room and looked around. So this was where much naked naughtiness went on?

Well, not today. Today it was fully clothed naughtiness.

Walter wheeled the tank over to the pool and tapped the glass. "Okay, little uglies, come on out for Uncle Walter so you can meet Uncle Principal."

The next few minutes were spent in an odd form of fishing in which Walter taunted grindylows and wrapped little grindylow appendages in wire to pull them out of the water and toss them in the pool.

As an afterthought, he tossed in most of the gillyweed, too, stuffing some in a plastic bag he'd brought for his own future nefarious purposes.

He watched the grindylows swim in the pool and made an urgent phone call to Principal Smith.
