New biome and leviathan idea

A new biome called the sand swirls, with a new leviathan called “the sand snake leviathan” where in this boime the sand moves around in the sand with rocky spikes on its back sticking out, and when it stays still it looks like a patch of large rocks, which will look similar to others in the boime that look almost the exact same, near the bottom should be blueprints or valuable ores , or even story progression! Anything that makes the player having to face the new danger worth it, to scan it you’d have to stand it by making it bash its head as it chases you in the sand, kinda like a boss fight mechanic but it only stuns it long enough to scan

Btw a little note the name wouldn’t have to stay the same it’s just an example that fits the boime idea

Could call it an antlion leviathan, similar to an antlion it could submerge most of its body below the sand and when it detects big movements or vibrations it would strike so like a mix of the ice worm levithan and the Crab snake

This idea is fire I just think the name needs work for either lol,
