It sounds like a silly question, but it caused way more discussion the other night in my Adventurer's league game than I'd care to admit…
In 5e, the prone condition is described as:
A prone creature’s only movement option is to crawl, unless it stands
up and thereby ends the condition.
A snake's only option is to crawl, and isn't capable of standing, as it has no limbs.
Is a snake (or snake-like creature) considered constantly prone?
If not, can such a creature be knocked prone?
