Spark is knocked unconscious by the rock.

The rug continues to chase the gold dragon wyrmling.  Attack: 14

Enraged, the wyrmling flies up and breathes fire on the rug and everything near it.

14: Rizo
9: Minty
8: Air Elemental
6: Spark
6: Allosaurus
6: Gorgon

Rizo utters a Mass Healing Word to get Spark back on her feet and heal Minty and himself by 7 HP, and summons Moni, his trusty, fiery Butterfly in the midst of the enemies, near the Gorgon (10feet around her take 4 Fire damage unless they pass a dc 15 Dex save). Having no instructions, Moni simply dodges any attack on her.

Minty’s turn

Rug of Smothering's Dex save: 22

Allosaurus's Dex save: 9

Gorgon's Dex save: 7

Giant Ape's Dex save: 17

The gorgon (now 61 HP) and allosaurus (now 30 HP) are caught off guard by Moni's appearance.

It is still Minty's turn.

With the allosaurus and the gorgon at each other’s throats and the wyrmling and the carpet similarly engaged, Minty turnshis attention to the Ape.

Minty's crossbow bolt hits the ape, but it is still standing (111 HP).

Spark launches two Magic Stones at the ape and tries to avoid becoming a statue.

Attack: 12 Damage: 11

Attack: 10 Damage: 12

Constitution save: 12

Spark's skin starts to harden, but she focuses and it changes back as she lands two hits on the giant ape (93 HP).

The allosaurus keeps trying to bite the gorgon.  Attack: 7 Damage: 17

The allosaurus fumbles as the gorgon tries to recharge its Petrifying Breath: 3

The gorgon tries to gore the allosaurus.  Attack: 15 Damage: 17

The chuul is still a statue.

The giant ape turns to Minty and hurls a rock.  Attack: 18 Damage: 38

With the gold dragon wyrmling safely in the air, the rug turns and moves towards Rizo but is unable to reach him.

Damage: 29

Rug of Smothering's Dex save: 14

Allosaurus's Dex save: 16

Gorgon's Dex save: 17

Giant Ape's Dex save: 17

All the creatures avoid the worst of the wyrmling's breath, but the rug and allosaurus are too badly wounded to survive it.  The gorgon (47 HP) and giant ape (79 HP) are showing some signs of fatigue, but are still standing.

16: Gold Dragon Wyrmling
14: Rizo
9: Minty
8: Air Elemental
6: Spark
6: Gorgon
4: Statue of a Chuul
3: Giant Ape

It is Rizo's turn.

Rizo casts Cauterizing Flames (special wildfire Druid spell of 2nd level) and heals Spark by 6hp and deals 6 fire damage to the Gorgon. Then he commands Moni to shoot the Gorgon, too.

Attack: 26 Damage: 9

Spell description: Cauterizing Flames

Flames burst out of your hands to heal and harm. Target two creatures, one takes 3 fire damage, and the other regains 3 hit points.

At higher levels. This spell deals and heals an additional 3 damage for each level above first.

Minty tries to dodge out of the way of the rock and manages to soften the blow somewhat, but not entirely.  He takes careful aim at the ape and returns fire, though he knows this is a war of attrition that he cannot win.

Attack: 27 Damage: 45

Elven accuracy die:14

((The number shown on the ape's attack does not seem to make sense and is not the same as if I hover over it.  It still would have hit, but can't tell if it was counted as a crit))

Stupid me read that the ape was targeting again Spark, therefore Rizo heals her... Well, a few extra HP haven't hurt anyone yet.
