Okay, so real sandworms aren’t all that horrifying. But in the world of Dune (And, to a lesser extent, Beetlejuice), they’ll sink the ground right under ya, pa. In the seminal real-time strategy game Dune II, they played a pivotal role in barreling through terrain underground and smashing shit up just when you thought things were all set up. Dangerous, monstrous things, indeed. Also, not to be confused with the Graboids in the movie Tremors. Those were badass, too, but they weren't sandworms. #nerd
