Yes, my idea is that the sand is dense enough that anything lighter than a huge gigaton worm would not feel the fluidity. Like insects walking on water.
Anyway, I just searched it, thinking that someone else might have an idea, and it turns out that the biological explaination is that they’re not worms, but legless lizards.
I don’t see how this thing could burrow into sand? It’s sand, not flour.
It’s the Sound they make and a phenomenon called Sand liquification . Basically it means that Vibrations and Air turn Sand in a liquid like state.
Ah, so that’s the “drill”.
Huh, that could actually work. Though unlikely at this scale
Maybe its quicksand with just the right density for worming.
The people run quick for quicksand tho.

Maybe the sand is the opposite of a non-newtonian fluid, is solid at rest but becomes basically fluid with vibration
Though I imagine sand would naturally behave this way if it isn’t packed too densely
