Im going to make a comment about these critters in a minute. Ive known about this particular movement from them for a long time and its only now that I decided to comment on it...

Whoever created the Ashu Hhinvi must have had a lot of time on their hands or just loved the soap "Days of our Lives"

"Like sand through an hourglass, an ashu hhinvi melts into a small dune upon the ground."

Now Ive got theme running through my head. Not fun. Not fun at all.
