The king croaks loudly and the bullywugs back off.  The bullywug in hide armor croaks some more to the rest of them.

Fane:

 [Suspending initiative...]

At this, the bullywugs let out a raucous chorus of ribbits and croaks, their excitement mounting.  They began hopping back, forming a wide ring in the muddy ground.  Their rubbery bodies glistening in the midday sun as they cleared space for the coming fight.  Those on the far shore swim across to get a closer look.

The large bullywug in hide armor steps forward, puffing his massive throat pouch in an intimidating display.  His leathery hands grip a crude but wickedly sharp bone axe  still stained with the gore of past victories. His beady eyes fix on Eron with amphibian stillness before he gives a slow, confident guh-rooook.  His neck pouch swells as he croaks out a steady rhythm, something like a song.

Fane:

The other bullywugs take up the rhythmic croaking chant, and soon even their king joins in.

Then, with an explosive ribbit, the one in armor slammed the flat of his axe against his own chest, issuing the challenge.

The bullywug warriors tap their spears against the ground, but some—perhaps showing off—lash their long, sticky tongues around the hafts instead, whipping the wood against the marshy earth with wet slaps or twirling them in the air.  The air is alive with the strange, primal energy of the swamp-folk’s ritual.

Eron is invited into the circle.  The duel is about to begin.  The large bullywug, appearing as confident as a frog can look, seems to be offering Eron to make the first move...

1. Eron
2. Aarp

[This will result in the expiration of the spectral tentacle... though it looks like the rest of the party has some freedom to reposition themselves as the bullywugs are distracted.  Anything more attention-getting than moving around risks being noticed, however...]

[feel free to veto/change what makes sense..]

Fane will whisper to Leo, "Take flight, find a spot to hide and watch, when its time, I will be going for the leader, the one on the frog. Hopefully standing next to him before he realizes it, thats when I'll need your help."

She hears the Bullywugs singing, and begins to sing her self. She will move up to the circle, as far as the bullywugs seem to allow and within 30 feet of the frog/leader if possible, and begin to sing... In Elvish, a deep, beautiful song, she taps on her sword to keep a beat, 1..2..3..4..

The song changes a bit, and she starts clapping the beat with her hands 1..2..3..4.., and she repeats the 'song' in dwarvish and gnomish, not knowing what languages their newest party member speaks, but hoping they get the point that some sort of coordination is being attempted.

Eron prolongs the engagement ever so slightly bending and positioning for the expected attack, ready with a two handed long sword attack if Aarp comes into melee range.

Attack 15 damage 9 slashing 5 force including favored foe.  (Hamstring if hit also -10’ speed)

Arlynn is surprised as Eron offers to face the bullywug champion. Now he stood encircled by bullywugs intent on killing him. Out of the frying pan and into the fire it seemed to her, but she was still fairly confident they would see this through. Discreetly she steps into hiding, ready to resume the fight.

Stealth: 8

Arlynn, at least one bullywug watches you out of the corner of its glassy eyes as you attempt to slip into concealment in the bushes.  [You can try again next round.]

As Eron steps forward and attacks, the bullywug lashes out with his axe, having readied an attack despite seemingly offering Eron first blow.

• Axe:  10  (Miss)

The big bullywug almost sidesteps Eron's attack.  It moves with a kind of unexpected and ungainly gracefullness, its thick belly and torso bobbing along atop its long froglegs.  But it is not quite quick enough and Eron's blade bites deep into one of its legs.  There is an angry chorus from the crowd.  

Aarp then inflates its throat pouch and offers a bloated rebuke of Eron.  The noise is atonal and painful to Eron's ears.

Fane:

 Eron, make a DC 12 WIS save, taking 10 psychic damage on a failed save, or half as much damage on a successful one. If Eron fails this saving throw he also has disadvantage on Constitution saving throws until the end of his next turn.

ROUND TWO:

1. Eron
2. Aarp

The blue-haired half-elf gives the beady eyed froggie an innocent smile, and as soon as it's attention is drawn back to the gruesome duel she again tries to slip away.

Another stealth: 18

Eron lands a solid hit but still reels as his adversary croaks out disdain for him.  He then focuses (Slayers prey) attacking once again.  “Where’s Leo?”

Attack 12 damage if it hits 7 slashing 4 fav foe 4 slayers prey 3 hunter’s mark

Aarp sidesteps Eron's latest attack, to thunderous croaks of applause. 

He swings his heavy axe at Eron, but likewise fails to connect, to ribbits of disappointment.

Axe:  10  (Miss)

Round 3:

1. Eron
2. Aarp

Eron with a flourish draws his bone dagger and attacks with both blades…

Action attack with his longsword 25 to hit, damage 8 slashing 1 favored foe 3 slayer’s prey 4 hunter’s mark  -10’ movement hamstring.

bonus action attack bone dagger 8 miss

[Since Eron gave the 'engage now' phrase about Leo, how do you want to handle the rest of us joining? Did you want to roll initiatives?]

One she heard the phrase, Fane would engage, by misty stepping onto the frog! :)

Though Eron misses with his dagger, he cuts the frog deeply with his other blade.  Aarp now appears to be struggling, to the furious astonishment of the gathered bullywugs.  He swings his axe wildly with two hands at Eron.  

• Axe:  24  Slashing Damage:  5

He connects, which briefly calms the nerves of the crowd...

... But their astonishment is compounded when Fane appears on the back of the giant toad in a flash of shimmering light.  "GLORP!" croaks the king as the bullywugs grip their spears and turn on these invaders.

[Resuming the original rolled initiatives, but rolling Fane up to the top as she is kicking off the festivities.  Misty Step is a bonus action so she still has an action available... Also, Arlynn was able to successfully hide in the reeds.].

Initiative:

1. Fane
2. Arlynn and Lyrric
3. Eron
4. Bullywug Leaders and Bullywugs

"Hello King, I am Fane" the ulv says, rubbing the brim of her hat with one hand, the other resting on her short sword hilt, "It was a good fight, but perhaps it is time to put an end to it? Let's call for peace before one of them becomes Hydra food? Most likely it will be Aarp" she says.

Charm Person on the King from her hat!

"It would be an honor to listen to you tell us the story of how you gained such a magnificient staff!"

[Leo will do a flyby as she was waiting for me, but since I didnt attack she will just dodge and fly back up into a tree]

[Potentially pausing initiative again for all but Eron...]

Fane appears beside the king and uses the magics embedded within her hat to cloud his mind with friendship.  The magic settled like a gentle mist over his thoughts, and the shift in his demeanor was immediate.  His tense posture softened, his wide-lipped mouth curling into something resembling an amused smile.  It opens its mouth and gurgles at her.

Fane:

 Below, the gathered bullywugs give a chorus of confused ribbits, their round eyes flicking between Fane and their king.

The king's gaze flicks down to the fight, watching as Eron and Aarp continue to circle one another.

Fane: 

 The king makes a motion toward - well only toward Lyrric as he is the only stranger other than Eron and Fane still within sight.

Fane:

 The king rubs his big belly in a way that appears to be a meaningful gesture in the conversation in frog-gibberish he is having with Fane.

Fane:

 The king appears to be inviting Fane to watch the rest of the duel with him.  Seeing that their king is not in any immediate danger, the somewhat confused remainder of the bullywugs are willing to go back to watching the fight, though some of them are not side-eyeing Lyrric as if they expect him to do something peculiar next.

[Lyrric and Arlynn are up.  If they want, they can continue to let the duel play out, or they can act, which will may put us back into mass initiative.]

WIS:  9

Fane smiles at the King, "You are so kind, and the perfect host." She will turn and sit on top of the frog, facing the duel.

"And thank you about my hat, it is most beautiful, possibly the most beautiful thing I've ever seen, but it is too loose on me, it's constantly moving around. Oh well, it is beautiful, and valueable."

She then adds matter of factly, "If you wanted to, I would give you my hat if you gave me your found club. I could use that to club to pound my enemies back at home!" she says with a smile, "It's obvious that the hat matches your eyes better than the club too. Right?"

And she will turn to watch the duel.

[holding off on any further 'turn' base things]

Not sure what is going on with Fane and the disgusting bullywug leader or what the current plan is, the blue-haired half-elf stays hidden, ready to join the fray as soon as there is any aggression other than the ongoing duel.

On his turn.

Action attack longsword 25 damage 15 total (favored foe, slayer’s prey, hunter’s mark) hamstring -10’ move.

Bonus action attack bonedagger 16 damage 7 piercing.

at the end of his attacks Eron sheathes his bonedagger freeing up his off hand…

With a pair of savage cuts, the green, bloated body of Aarp spins and falls into the sandy much of the beach.  There are croaking gasps and mutterings from the assembled Bullywugs, and the King tut-tuts and disapproval.  

Then the king shrugs, looking at Fane.  He taps his black staff on the back of the giant toad, proclaiming something in a series of loud urps and ribbits.

Fane:

 The bullywugs, still seemingly put off by the unexpected death of Aarp, begin to crowd around Eron and Lyrric, spears at the ready...

[Any more ideas?  ...  if not...]

Initiative:

1. Fane
2. Arlynn and Lyrric
3. Eron
4. Bullywug Leaders and Bullywugs

Fane will stand and point at the water, "Another Hydra, much larger! Run away!" as multiple hydra heads multiple hydra heads appear in the water, 10 feet SE of the bullywug directly east of Eron.

"Oh great king, may I borrow your staff, perhaps I can defeat the Hydra with it!" she says, looking for anyway to get the staff without outright killing.
