Sorry for the monster post again, but with several suggestions along with a half dozen questions…….not much I can do about that.
I always feel like the more I write, the less players read carefully and actually catch on to what I’m saying, but trying to be as detailed as possible while keeping the update short proves difficult at best sometimes.
Anyway……
Are my maps and other aids difficult to comprehend? Because Loyn is still with the main group. He’s the L next to the chimney.
Anyone can try to mimic the sound of a creature, though I might give a better chance of success to someone with experience in such things.
I assume scouting means peeking in for a quick look without attracting attention from the monster. Therefore, you have no idea how much chain hangs from the manacle. Unless someone wants to get a closer look? 
Also, since the scouts have been there and back twice already, you can assume there is no need to provide more details about your approach. No need to muddy the waters more than I already have.

Splitting The Party Again
Early Afternoon, Warm Clear
The Gnolls growl and gnash their fangs at each other, steadily succumbing to the violent effects of the psychoactive plant they’re chewing. This makes a few others nervous, wondering if they will need to fight them too, eventually.
Loyn hold Bugs up from the hole for a moment, the energetic Gnome’s mouth and feet still churning away while he’s suspended there in mid air for the moment at the behest of the dwarf.
A few more suggestions are made on how to deal with the threat inside the cave, but none of them sound any better than Daliedhur’s idea of simply firing arrows into the thing from a distance. Though Magdal and Keya believe that is probably against their Ranger ideals, both eventually agree to the unsettling plan.
Bugs wants to sneak around by himself, so Loyn lowers him back into the hole and gets Pimlan ready to climb down behind him. Renna stands at the ready in that area as well.
Tammuz shakes his head at the idea of poisoning a 900 pound creature, wondering how many gallons of poison that would actually take. The priests in the group also give the Dwarf a concerned look after such a horrifying suggestion.
Once the plan is agreed upon, the Gnolls follow the rangers and the elves down to the area of the cave mouth, wondering if there will be some kind of signal to attack once they arrive.
On the other side of the ravine by now, Meinhardt suggests his group move to the next copse of trees to reach a better vantage point to enter the cave. When he looks back to the opening where the Bugbears live, he sees a massive figure standing there waving for his foursome to join it.
