Instead of scattering these creatures on a beach, why not release them into the arid, wind-swept open spaces of Antarctica as well? Wait a decade or so until its ice caps have melted away, and watch them scamper about over newly revealed soil. With pollens, seeds and alien microbes gestating inside their plastic yellow tubes, they'll plant new orchards and forests, maybe a farm or two, like an army of robotic Johnny Appleseeds.
How about dropping them off in Chernobyl? Using the ample ambient radiation as their power source, they'll proceed to deposit phytoremediating flora and fauna. In future sites of nuclear disasters, they'll become part of the primary emergency response protocols.
Let's also send them to Mars or Titan or some extrasolar planet. A new breed of intergalactic planetary landscape architects capable of exploration and terraforming: fast, cheap, and out of control.
Powered this time by dust devils, they will seed entire ecosystems, cultivating and pruning for centuries. And even when the planet has been fully colonized, they will still be marching across the landscapes they had created. Inorganic and extraterrestrial they may be, no one is going to dispute that they're an inalienable part of the planet's natural history.
They will also become central figures in the colony's mythology as well. Around machine oxygenated campfires across the planet, terraformers will entertain themselves with stories of The Creation that might as well have been written by Ovid. “The Animaris geneticus wasn't manufactured by NASA, but rather the result of incestuous and bestial trysts between the Gods and the First Colonists,” is how future Aesops and fabulists will start to spin their yarn.
As a way of maintaining social cohesion in a still unforgiving place, colonists will scare their extaterrestrial children with ghost stories of disobedient youths snatched from their beds in the middle of the night by these ancient beasts, who then imprisoned them inside their skeletal frame as their pneumatic creaking, clicking, trilling howls fill the terraformed air.
