Seeing the lack of anything immediately dangerous in the water, Mist jumps in and swims down to see if the plant's movements are an indication of a tunnel under the water.

Kraven waits to see what happens to Mist and then will jump in after him.

Mist there is a tunnel that leads under the "exploding room of death"

Aubric looks to Druquilla "That little guy really has no sense of self-preservation does he." 

Mist keeps swimming ahead until he either finds the other end of the tunnel or sees something that would make him want to turn back (an obstacle or something potentially dangerous).

"Who knows," Druquilla answers back then turns her attention back to the crab.

"Okay you are not hungry," Druquilla says calmly to the crab. "We mean you no harm. Show us what is bothering you and we will help. Is it something in the pool?"

Mist swims back to the surface and spits a stream of water at Tordek. "Jump in! There's another room beyond, there is! It's just a bit of swim down and around. Let's go!" And he disappears beneath the water once more.

Anyone who goes needs to make a athletic check DC 13.  Failure you still make it, but take a point of exhaustion.

"…Go, if you want to. I'll watch the crab while you guys jump into the pool." Gintarou holds his weapon and keeps an eye on the giant shellfish. He would be the last one to enter the pool.

Athletics:12

(He probably gets stuck in the tunnel lol)

Yes Gintarou gets stuck as he is trying to make his way, forcing him to expend too much energy.  Take a point of exhaustion.

"It seems we have no other choice, follow the small one, go go," Druquilla motions for the others to follow Mist, once she and Gintarou are the only ones left she will nod to him then dive into the pool. Once in the water a smile forms on Druquilla's lips as a sense of longing is finally released and loses herself in the weightlessness of being underwater after so long, but after she feel the pressure waves of Gintarou entering the pool she collects herself and follows the others to the next room.

Athletics: 1 

Druquilla you do not take the point of exhaustion, because you can breath underwater.

Athletics: 8

Kraven Athletics: 20

Kraven enjoys his swim through the water it almost feels as if he is flying through the air reminding him he needs to do more of that.

 [OOC: Sigh not sure why the dice roller warning is coming up.]

Athletics: 15

Zan secures his sword and prepares to take the plunge.  No stranger to the water, he looks confident as he dives.  But as he enters the tunnel he cracks his noggin on the stone, causing him to falter as he rushes to find the surface.

Aubric and Zan both take a point of exhaustion.

Gintarou pulls himself out of the water. He lies on the ground, gasping for air like a whale strands on the beach. "…I should have known this. ****! I should have known that cursed tunnel is made for kids, not for grown men! Not for me…"  He rests there for 1 minute then raises his head and looks around. "…Hey guys, are you still alive?"

Zan coughs as he emerges, spraying anyone near him like an orca.  "Never better," he chokes. 

Kraven pulls himself out of the water easily enough and then ruffles his feathers as most of the water wicks off his body and take a look around.

Perception: 15

This small room has long long dead bodies in it, and a basin with some water in it.

There is a pathway out, you can feel a cool breeze come through it.
