  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.

    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
