"Oo, sounds it!"

Marel gave them a distance and direction from shore, and the building lets them out onto a beach. Margaret can just stride into the surf and keep going; she does so, laughing as the waves start going above her head.

Silv laughs and dives into the water as a large seal.

"I wonder if we can hear each other alright," says Margaret.Her voice is distorted by the water but her speaker is of course the same as always. 

"I can hear you!" Silv calls back, though her voice is also distorted.

"Oh good, I can hear you too!" They swim out past the continental shelf and start angling deeper. A school of fish changes direction in unison to avoid them.

"Helpful!"

"Do we know the ship's location?"

"Marel gave me a compass heading and a distance. At this rate we should be there in, let me do some math . . . half an hour?"

"That works out fine for me."

They swim for a while, and eventually Margaret asks, "Can you do a form that has sonar? It's probably our best bet for finding the shipwreck in this murk."

She nods, shifting into a large dolphin. Squeak!

"Shipwreck's over there," she identifies after a bit, before giving more detailed information on distance and all.

"Awesome!" Then they can head over there and spot the remains of a three-masted sailing ship, crunched up somewhat by the storm that sank it and somewhat more by hitting the bottom.

She flits around, exploring, finding interesting items for Marel, memorizing things, keeping an eye out for any approaching sea life - generally having fun, though.

Margaret does likewise! There's lots of cool stuff, both from the ship's equipment and from its cargo.

There's also a giant squid! It thinks Silv is edible!

Silv turns into an even gianter squid! And waves her tentacles, agitated, doing the squid equivalent of cussing someone out for being rude.

Oh no! This is not at all what normally happens when this squid tries to grab a tasty dolphin. Nope nope nope goodbye, have this ink cloud as a Good Job Being Scary present.

Margaret started heading over from the other end of the ship as soon as she saw unexpected movement. "Silv? Are you okay?" She churns the water with her tail to disperse the ink cloud until she can see what's going on.

She laughs and turns back into a dolphin. "I'm fine. Just a hungry squid."

"Ah, and you were out-squidding it. Exciting."

"Sometimes needed. But being alarming's better than getting into a fight, with most things."

"Definitely. I suppose you could sort of make the case that it was minding its own squid business and we showed up and surprised it."

"Yeah. I don't mind giving big social predators a chance to play, but it's - rude, to hold an animal being itself against it, you know? And squid aren't wolves, they don't think romping around is great fun."

"Random wolves want to play with you when you're a wolf? I wouldn't have guessed that; it sounds adorable."

"It is! And it really depends on how well fed they are and how much I look like a threat; still, I get any chances to play."
