Sometimes we may notice tiny pockets of air building up in the area where the sand touches the glass. Occasionally you'll see worms, or pods, or just an empty tiny cavern to peer at, but this time I saw something different. This is a typical view, captured with my iPhone:

But now that it caught my eye, I bent closer to get a good look. And I discovered valonia growing under the sandbed. That's somewhat hilarious to me. Spock loves eating it, so now I want to say she's hoarding it like a hamster in her bedding.  hahaha I'll have to unearth it so she can devour it.

Never seen anything like it. Have you?
