C'mon we gotta head back now
P.S. I'm gonna be drawing the new comic live on twitch in about 10 hours from this post (gotta sleep first) if you're interested!

Nitpick time: the sand castle would probably not be disturbed that much since no atmosphere means the plume can't stir up any wind. I guess if it's really close though.
Well if we're going to nitpick: It probably isn't possible to build a sand castle on the moon without some special tools. Everyone who's ever made a sand castle on the beach knows you need some water in the sand to make anything. Otherwise it's just a pile of sand and won't hold any shape at all. Now the dust on the moon is a combination of bigger and very small particles, so it kinda acts like flower on a small scale, thus footprints are visible. But I don't think you could form any large structure, anything above a centimeter or so would collapse into a pile.
With some special tools you could put the moondust in a mold and apply pressure, that way it would maybe hold it's shape. But it would be a big challenge.
On the other hand, the combination of microgravity, no wind, and more jagged sand particles might lead to better cohesion
It's hard to say, but I wouldn't call the moon microgravity, it's at 1/6th of Earth gravity. The moon particles are more jagged and also often statically charged, which may help or be a hindrance. Plus there's the whole spacesuit thing, those gloves make it hard to do anything, let alone build a small structure with fine details like a sand castle.
