What shall we do with the Drunken Sailor – a Nautical themed set of Adventures in the Moonshae Islands

The Bullywug attacking Griff flings its hands up in the air and collapses backward as Tiro drives his trident deep into its back leg "frog leg anyone" he chortles. 

Seeing his proposed target drop, Zin quickly pivots and aims at the Bullywug attacking Gilly. However as he pivots his foot slips and the shot goes wide.

The Bullywug attacking Hallard continues to press forward {Spear = Attack: 17 Damage: Unable to parse dice roll.} and {Bite = Attack: 22 Damage: 2} and drives his spear deep into the Storm Genasi's body who collapses with a groan that quickly becomes a gurgle as he falls into the swamp.

The Bullywug attacking Thrash thrusts with his spear {Attack: 11 Damage: 9} and also attempts a bite {Attack: 13 Damage: 5} completely ineffectually. In response Thrash simply pounds the creature into the marsh.

Gilly and Griff - you're up.

Seeing his assailant going down, Griff continues to backpedal to shortbow range & target the creature attacking Gilly.  Letting rip with a telling sneak attack arrow at the unsuspecting creature.

Attack: Attack: Attack: 12 Damage: 9  + bonus sneak attack damage: 6

How many are left and where are they?

Two left on Gilly and Hallard - all easily within 60' and probably actually 30'

Hallard will send the tentacle after another frog creature if can reach.

Attack: 22 Damage: 5 Cold Damage

He will then follow with a blast of force at the same creature.

Attack: 18 Damage: 5

Feeling overwhelmed, Gilly takes a defensive posture.

With a croak the Bullywug presses home its attacks {Spear = Attack: 12 Damage: 4} and {Bite =Attack: 7 Damage: 3} against Gilly who desperately dodges but is unsuccessful as the spear pierces him in the shoulder. He collapses into the swamp.

Tiro and ZIn - you're up in that order.

Tiro, still feeling the rush from such a successful melee,  lets out another blood curdling yell and drives towards the Bullywug that was attacking Gilly and drives the trident deep into its belly.

Attack: 18 Damage: 7

(If Tiro can't get there, but can get to within 20', he'll throw it at the Bullywug - same attack and damage rolls and as a bonus action, Tiro'll draw his shortsword and continue advancing on the Bullywug).

 (If that has killed the Bullywug, then he'll pull Gilly up out of the swamp instead of drawing his shortsword.)

Zin, Tiro manages to thrust his trident deep into the belly of the Bullywug but despite the blood pouring from its wounds it is still standing.

Seeing the creature still alive he fires an arrow at it

Attack: 22 Damage: 5

The remaining Bullywug which was attacking Hallard looks at his unconscious body croaks victoriously and hops towards [1-Griff, 2-Thrash, 3-Tiro & 4-Zin) [1] Zin and with a mightly hop leaps towards them and thrusts two handed with its spear {Attack: 19 Damage: 7} at the same time as trying to bite them {Attack: 21 Damage: 4}. Tiro yells "watch out"  as the Bullywug launches itself at Zin. Zin manages to whirl in time and get his bow up to stave off the creature who as it lands [5] realising it is the only one left and it is facing four foes - one of which is a large angry lizardman - starts to back-peddle away.

Hallard (Death Save) Thrash, Gilly (Death Save), Griff, Tiro & Zin. 

Death save: 16

Thrash would raise his flail high above his head and swing hard with his barbed weapon toward the last bullywug. The blades would whistle through the air as the lizardfolk swings and hisses in anger...

Attack: 24 Damage: 9

Bits of Bulltywug brain are spread far and wide. Thrash's forked tongue flickers out and wipes a goblet of brain matter off one of his eyelids.

So what are you doing?

As the last Bullywug dies, Thrash would quickly turn to Gilly and move to his side. "This one too useful for food." He would say as he attempts to stabalize Gilly.

Medicine...13

Zin steps quickly to Hallard and kneeling down he attempts to stabilize him.

Medicine 11

Thrash takes a quick look around the marsh and spots a strange yellow moss. He grabs it and starts stuffing it into Gilly's wounds. Much to surprise of anybody watching the bleeding stops. Meanwhile Zin adopts a more traditional but equally effective method of putting a bandage on Hallard's wounds.

As the two are tending to their fallen comrades, you all hear a deep boom which sends shivers of dread up the spines of all those who are conscious.

"Well it doesn't seem we can go too far with all our wounds.  We had better look for somewhere defensible to tend to our wounded." says Griff.

"Does anyone have any idea where or what that sound came from?" While trying himself to see if he could make sense of it (Perception: 21)

Zin looks up from his work with Hallard trying to determine where the sound came from and what it might have been.
