Buppido gives a sleepy grumble, but Jimjar stirs himself, coming to join Galingal at the side. "What's that?", he asks, pointing at the creature swimming up alongside Stena.

It's just keeping pace with her though, so he's more curious and confused than alarmed.

@Stena:

Stena switches to a back stroke to call over to Galingal and Jimjar,

"Oh, meh buddy was here in the water. Neth is joining us. Ye should too, there's something on this rock over here we should check out. Come on, it's not cold."

Deception?: 8 (was 15)

"Get out of water," Galingal calls to Stena and Neth. 

He looks over at Jimjar and shrugs.

"Big fish."

Galingal then puts down the net and fishing spear and gets one of the poles they used to move the boat earlier and reaches out, slapping it down on the water closer to Neth.

Stena's voice and behaviour registers with Galingal finally.

"Stena head not right," Galingal says to Jimjar. "Too much friend."

((Let's see what an active Insight check gets Galingal? Passive he knows something's off already. Nature check as well?))

Gal Insight: 21  

Nature: 13  

"Too much friend? Yeah... wouldn't consider her the friendly type. Bet you five gold she been-", Jimjar twirls a finger next to his ear, sticks out his tongue and crosses his eyes.

Galignal, if that's deep gnome gambler code for 'been magically charmed by a fish who got her into the water for nefarious purposes', you're not taking that bet. 

You've dealt with cloaker's before, these look like much smaller, aquatic versions of those. Whether they're any relation or not, they aren't the sort of thing that she ought to be swimming about with.

Neth is very comfortable in the water. However, he thinks, he is very uncomfortable in the water with this thing talking to him. 

 Neth also makes a direct line for the pole offered to him from the boat. ((His swim speed is 40 and he can breath under water if that matters))

As he is swimming, possibly for his life, he looks back, mouthing something hard to understand, and desiring the beast to be frozen.

((Make a con 15 saving throw, if you fail take the damage and disadvantage on next weapon attack))

Neth is bitten by the competitive spirit, forgoing chickens out on the race against the dwarf and her friend, instead grabbing Galingal's offered oar and diving under the surface and striking out for the rock, shooting underwater at an impressive speed. As he passes Stena and her good buddy, he attempts to freeze the creature.

"O-o-ww-wie! T-that guy's f-fast a jerk!", Stena's buddy remarks as Neth blows past them calls ice down on them, teeth chattering from the cold. "I think your buddy just tried to hurt me! Time for my buddies to come play too!"

Neth is 40 ft from the boat, and 15 ft from the stalagmite, it's unsure if he's going to be able to scale it. next to the boat.
Stena and her buddy are 10 feet behind him, so 30 ft from the boat and 25 ft from the stalagmite.

Lia tosses and turns in her sleep. She hears Neth’s call for ‘help’. Or was it in her dream??… She hears Galingal call her name!… that one cuts through…

She sits up in bed with a start, eyes wide in the dark looking about. She hears voices up on deck…

Remembering her dream, she suddenly tries to see and reach over her own shoulders, turning about, this way and that, like a dog trying to chance its own tail. She pats down her own shoulders and shoulder blades for some phantom that’s not there. A figment of her imagination.

Coming back to reality, the commotion above deck continues, and she grabs her Lyre and heads up…

Galingal watches what’s happening in the water for a moment, seeing Neth cast some sort of magic at the one ray like creature.

”That fish. Those fish. Changing Stena. Stop them.” Galingal says to Lia, Jimjar and Buppido.

While he doesn’t let go of the pole, He only holds with one hand and points with his other hand back at the ray swimming near Stena, the one Neth froze. 

As he does, the sound of a deep bell sounds under the water, vibrating in the ray’s head.

Stena turns around and looks at her best buddy in concern. She then turns and yells back at Neth,

"What is wrong if ye? Just because ye lost a race ye attack meh buddy?"

To her buddy she says,

"Aye'm really sorry, aye don't know him well. He just jumped on the boat, really."
