Sandworms in Dune: Awakening are scary as hell. They're huge, they're fast, and they're summoned anytime you cross the big, sandy gaps between rocky areas in the desert because they can sense your itty bitty footsteps. Seeing the dunes shift as they tunnel through the desert is alarming, and seeing them burst through the sand and roar is downright terrifying.
There's another reason to dread sandworms in Dune: Awakening: if they swallow you, you lose everything you were carrying. Permanently.
