Puddles,
what on which stuff can float is a puddle. Grendel doesn't like water, he remembers his one and only bath with no small terror. Grendel hates puddles. Even so, he will explain some of the finer points. First we might simply talk about how nice puddles look and how the soothing sounds of lapping waves can calm an anxious mind. If you don't want to listen to Grendel right now, but like the sound of lapping water, go away.
