Please let us know if you run it! And yes, I would play with the encounter mechanics. If we had more space, I would have suggested more details for turning a carrion crawler into a velvet worm (at least one unique attack, shooting out sticky slime), but we thought to keep the mechanics as light as possible for this version.

Absolutely! I think the reference to the Carrion Crawler plus the description of the effects of the silk are good enough to come up with a quick adjustment. Though I think the prospect of it being able to grow to larger sizes and the fact that there is a hundred other eggs about to hatch already turn this from a “regular monster” into something a lot more interesting. Also great for sandbox play as a consequence to not dealing with the problem right-away!
