tsuwm: More to the point, what constitutes a good week on wwftd?

wwh: That is the dearest little story! You and that dead fish under your pillow! Maybe you'd been reading stories about the natives fertilizing their crops with dead fish, and you were sort of fertilizing your dreams. On the other hand, were you in the habit of sleeping with various objects under your pillow? The Fish Fairy theory, too, sounds plausible. Still, just thinking about a little boy with a fish under his pillow does sound like the beginning of a fairy tale. Wonder what Maurice Sendak would do with your tale as a hook?

And, speaking of fish, isn't there a word for how the scales of fish fit over each other at the edges? It wouldn't be something like imbricated?
Not too many people seem to read Weekly Themes, but I hope someone can make a comment about fish scales.
