While Gokudera and Yamamoto are competitive, they never really... yell over each other. It's just bickering and laughing and grumbling. Yamamoto is as calming as his Rain flames, ever talented at abating the anger he sparks up in Gokudera most of the time. If he isn't outright holding him back from attacking someone.

At least a Namehaga is also cool. Gokudera is game for dressing up and playing jokes on his friends. His sense of humor is strong and strange, even if most often he acts too grouchy for anyone to see it as a possibility.

"Ack! Idiot!"

Gokudera's plunging his hands in, but of course Yamamoto scared them. He's moving forward, swimming into deeper water and opening his eyes in the murky salt water. It's really no use, and his head pops out with a splash. "You scared them aw-!" And he's suddenly back under the water again before surfacing closer to Yamamoto and holding what looks like... an eel?

The length of slimy skin stretches under water and he blinks at it. Does this count?

It doesn't, as a strange mass of those eel-like tentacles breaches and splits open to form a single eye. There's a voice to accompany the creature, and Gokudera hastily drops whatever part of this alien that he'd grabbed to listen. "Sorry!!"

Now... uh. It stares at them, and Gokudera sheepishly grins. "We're just looking for fish."

The alien makes a gurgling noise and starts to sink back into the water. Hopefully it wasn't too irritated.
