Coming up behind them, the other three - Chase, Myrtha, Theran - should roll DEX (Stealth) checks as well, and roll with ADV because Aanbo is inadvertently serving as a distraction (which means a straight roll for Myrtha).

Myrtha clanks along with much-quieter Chase and Theran behind the group of humanoids, slowly catching up until they can see what the troglodytes are dragging: what appears to be a captive person bound hand and foot. Whether the person is alive or dead is unclear. The troglodytes hear Aanbo's crunching and Myrtha's clanking, so there is no surprise. They drop their captive (much as the party left Reptile) and prepare to fight.

Note: the big rocks toward the bottom of the map are boulders that block line of sight (they're about 7' tall) and could provide cover, but can be climbed onto for a higher vantage point.
The troglodytes Trevor and Ted are focused on Aanbo.

Myrtha rushes forward and slashes at the troglodyte Terry, but the monster dodges each swing. Coming up just behind her, Theran steps in and thwacks Terry with his thickened staff.
Terry takes 7 bludgeoning damage.
Terry tries to claw Theran, but Myrtha thrusts her shield in his face, giving Terry DISADV on his first attack. Irritated at Myrtha's interference, Terry turns on her with a bite attack and his second claw attack.
Seeing Theran's heavy blow, Tommy runs over to attack the druid, too, attacking with jaws and claws.
Ted and Trevor, meanwhile, remain focused on Aanbo. Ted rushes straight toward the monk, while Trevor jogs to the side and dives out of view into some thick underbrush.

Theran takes 3 slashing damage.
Terry snaps at Myrtha but misses.
Terry slashes Myrtha with a crit claw attack.
Myrtha takes 7 slashing damage.
Tommy slashes Theran for 3 damage, but his bite and second attack both miss.

Aanbo dodges Ted's slashing claws, but he steps into the vicious teeth.
Aanbo is bitten for 5 piercing damage.
Chase exhales slowly and releases the taut bowstring. The loosed arrow leaps across the Dim Forest and punches into Terry's neck.
Terry the Troglodyte takes 5 damage and falls, gurgling.
Choking from Ted's foul stench, Aanbo attempts to strike back at the malicious monster. At first his attacks are slow and ineffectual, but in the end he is able to kick Ted in the shoulder with a solid blow as the troglodyte is dodging his staff.
Ted takes 4 bludgeoning damage.

Aanbo must start his turn with a CON saving throw, due to the trog stench. Myrtha and Theran will need to do this on their next turns, too, if they remain adjacent to a living troglodyte.

The DC is 12. If, after the additional roll, Aanbo still failed the CON save, and that means that Aanbo will be Poisoned. If Aanbo's Poisoned, that means Aanbo's attacks have DISADV. Aanbo's already missed with the staff attack, but for the unarmed attacks, I'm going to let you choose. You can:
a) use the 11 and 16 as the DISADV roll for the first attack (so it will miss), then roll 2d20l1+4 for your second attack.
or
b) roll a second roll for the first attack (which is going to miss, with an 11), and roll a second roll for the second attack (which will hit if the second roll is equal or higher than 16).
If Aanbo's Poisoned, choose one, then make the rolls.
If I still fail, I will also apply the 11 and 16 to the first unarmed strike and roll another set of 2d20L1.
EDIT: As he has succeeded, I'll take the 11 and 16 as two separate rolls, and only the 16 hits.
