The iconic monster in the movie Tremors, graboids live beneath the sand.
You prompt is GRABOID
On this lonely rock
Marooned in a sea of sand
Death by worm awaits
They hunt by sensing the vibrations of creatures walking above them, swimming quickly through the sand and breaching the surface to grab their prey.
Made of appetite
to swallow all. Where do they live?
U S of motherfucking A
Sand worms grab what they can.
But Back to the future hoverboards
Drive them crazy.
