Cade really, really did not want to follow after seeing Immo's display. But seeing no others left except the drow and nightmares, the goblin made a break for it after the others, takes a breath, and hawk dives off the side into the murk. Unlike the others who surfaced immediately, he tries to avoid it, and surface only just enough to try and peek past the crap.

Stealth: 4. 

Perception: 4.

At least that was the plan before sludge gets into his eyes, burning his eyes enough that he starts flailing around complaining about it! 

Everyone fell splashing down, falling deep into the water, their apparent desire to surface immediately., splashing around in excrement, they had all just barely missed the spiderwebs above. And looking up, Crispy and Immo would see that the Drow Posting above was impossible to see from this angle, between the darkness and the spiderwebs obscuring vision.. it was a clever spot and ideal for ambushes. You can see that you all fell roughly in the middle of the pool, the sheer cliff to the south of you, with dry land  about thirty yards in every other direction. 

the rest getting water clogged in their eyes, though not to nearly the same degree as Cade, who's eyes stung with excrement, being thrust right into his eyes by the way he had dove in, and poor luck in where he landed.

Silently, and undetectable now that they had surfaced, the Grey Ooze flowed through the water, as if it were a part of it. Crispy and Immo being the only ones to notice. The ooze swam up towards Jimjar, pulling him into it's center. Jimjar began dissolving inside the ooze. (Taking 12) as did his armor and weapons.) As you all become aware of this, you hear a psychic mental screeching, coming from the ooze as it cries out "FLESH FOR THE FACELESS LORD!!!" stunning everyone except Crispy and Immotichey. The rest too paralyzed to react other than moving.  (by this i mean you failed the surprise round :P so you have no combat turn, but I will allow you to move.)

Initiatives:

Ooze: 7

Crispy 20 | Pocket_AT 4 | Mehmen 5 | Saute_Monkey 9 | o_Merlin_o 11 | Penguini 13

"There's something in the water!" Yelled Crispy, staring aghast at Jimjar INSIDE an ooze. Gross. "Spells only! It'll dissolve our gear" Crispy starts backing away from it.

Chubby: “What in tar nation is THAT?!  Crispy, what the hell is that?  Is that a blob of Drow excrement?  Maybe a fire will make it go away?”  He scrambles to swim away from it, not entirely sure if he can attack it. Or did that matter, whether he even knows how to swim. All that body fat makes him float like a cork, though. 

"It's an ooze! Don't touch it with your weapons, it'll corrode the metal! Fire spells at it!" She yells back to the casters. "Or it's your mom, i'm not sure which!" She snorts at Chubby.

As crispy snorts, some of the dank water enters her nostrils on the return breath. Chubby manages to swim as deftly as an overweight seal.

     Being relatively at ease in the water, Immotichey tucks his arms at his side and uses his powerful tail to propel him through the water - reminiscent of a crocodile. Once at a safer distance he notices the gnome looking a bit worse for wear. He offers him some aid in the form of healing word (7 healed, bonus action).

     With that done he turns his attention to the creature engulfing the gnome. With a word, his hand ignites in a magical fire which he immediately sends to the ooze.

Produce flame Attack: 16, Damage: 7

The ooze engulfs in flame, ironically enough sparing Jimjar from the flowback. The ooze doesn't move however, continuing to digest Jim. By this point, all of jimjars clothing and gear was beginning to become unusable.

"How do you like your deep gnome? Well done? Or Crispy! HAH!" Crispy slams Immo's shoulder. 

Arthasis crashed into the water and only moments later, while he still was under water, the warlock heard a number of muffled splashes signaling to him that the others followed his lead. It took him a while to get to the surface being dragged down by his gear. When he finally made it, he started to swim for the shore as fast as he could, nobody could tell what things were lurking in this lake.

Hearing Crispy’s shouts he suddenly realized that they were still in all kinds of trouble and Arthasis noticed that Jimjar struggled desperately inside the murky water. Asking for Guidance he tried to make out any dangers.

Perception: 23

Cade shakes as much muck as he could from his eyes. Seeing Jimjar in trouble, Cade ignores the warning and wades in closer to try and pull him free. "Hold on! I got you. Just hold on!" He calls out. 

Athletics: 16.

Cade has to grit his teeth to keep from crying out from pain. But if he can get a hold of him, the rest of what little movement is put towards pulling the melting gnome as far away as possible from presumably the source of the voice. 

Bonus Action: Disengage (Only if he has enough movement left AND has a hold of Jimjar.

The ooze continues to digest the Gnome, unperterbed, until it was healed, adding more flesh to be digested. Those who could see at all, would see Jimjars face deteriorating, only to heal back, and disappear again, after the healing spell. (Damage to Jimjar: 7)

 Most of Jimjars flesh disappearing, the muscle exposed as it began to be devoured. Jimjar was somehow still alive, but barely. Suddenly cade's arm sank in, trying to pull Jimjar free, unfortunately he only suceeded in tearing off both of Jimjar's arms, having pulled too hard. And sending cade flying back several feet.

The ooze, realizing it's current meal was almost over, lashed out towards Arthasis, suddenly covering the distance between them like it was nothing. The water was it's natural terrain, it was a fish, and everyone else was fodder. It screamed that same psychic scream at you all.

Instead of pulling Arthasis in however, it lashed out with tendril like amorphism, several tendrils lashing out at him. (attack roll: 23)

 It's tendrils coiling around his face and neck. (Damage: 7) and as the tendrils made contact, his flesh would burn like it had been struck by lava, feeling the acid corrode parts of him. (Acid Damage: 9)

 The ooze jiggled in euphoria, this all being the first flesh it had consumed in centuries, momentarily freezing in place, and seemingly stuck in raw lust.

Barely seeing the shore though the dim light, Evrik musters the strength he has left to begin moving towards shore. Given the gear he was carrying and his discomfort in the water, it was more of a loud display of splashing than anything else, but somehow he managed to keep his head above the muck and make progress.

As he flailed through the water he heard the exchange between Crispy and Chubby and looking back made out the commotion around the ooze. Then he saw the flame erupt but the creature continuing to advance, now towards Arhasis. The adrenaline pumping, he moved with renewed vigor towards the shore.

     Mixed emotions begin to flow the lizardman as the gnome begins to dissolve and is pulled apart by an attempted rescue by Cade: A shame. He was beginning to be useful. A lost cause now, it seems... Oh well, one less to keep alive... Hrm, that could have been a good snack.

Crispy chirps a quick but loud bark of disgust looking at Arthasis' face after the attack. "That's gonna leave a mark! Either kill this thing or lets get the Hells out of here!"

Chubby, resembling a bobber, is rapidly following behind Crispy in skeedaddling away from the GFST (“Giant Floating Shart Turd”, Copyright 2018, all rights reserved).

I continue to back up, pushing Chubby with me and whoever else is next to me that's melee, while grimacing at the fate of Jimjar.

Crispy and chubby reach shore.

Arthasis felt the burning sting as the ooze lashed out against his face and with the greatest urgency the warlock tried to get some distance between him and the aggressor. He would Disengage and continue to swim for the shore, realizing it was his best chance to survive.

After reorienting himself and realizing he had only pain, his own melted armor, and almost completely corroded arm to show for his effort. Cade gives Jimjar one last sorrowful look before swimming for the shore at top speed(30ft dashing in difficult terrain).  And until he was on the shore, he doesn't look back for anything.
