Also, the Sarlacc doesn’t really count as a sandworm. It’s tongue/mouth/thingy looks like a sandworm, sure. But the actual body (*sigh* as shown in the expanded universe and in reference books. I’m so sorry) is more of a…fleshy…plant root thing. The point is it’s not worm-shaped and it can’t move.
It’s missing the smallest sandword - Star Trek 2: The Wrath of Kahn. FAIL>>>
These seems…inaccurate to say the least. The sandworm in Beetlejuice is punched at one point, and in that scene it looks like it’s barely large enough to swallow a human whole, and even then it would be eating something as wide as it’s head. Sandworms in Dune, on the other hand, is described at one point in the book for having a mouth 80 meters wide. So…yeah. Not really to scale I guess.
This is fail, you are telling me that a worm that flew an entire space ship inside of is smaller than a worm that they rode around like a giant horse in “Dune”.
