[Ochako was thinking about it, honestly, just light refraction in the water would have made her aim way worse. It's a marvel she hit the beach, really...

She's keeping low, close to where the shoreline suddenly drops off into the water, unwilling to go closer for fear of beaching herself. Ochako comes to the surface often, but tries to keep herself hidden. Humans are...nasty. They toss their filth onto the sand or in the sea, and Ochako's had to rescue poor gulls, turtles, and seals that have been caught in that grime countless times. The first few times were a fluke, but after a few weeks...she's started to come around and rescue or save various sea life from humans and their nasty nets, traps, and trash.

Huffing, she flutters her tail and narrows her eyes. The nerve!! Her tail is as real as any! And even if it's not the prettiest or shiniest with abalone belts and seaglass loops that the more luxurious merfolk have...it's fine! But...w-wait. Buying them?? Do these humans...cut off mermaid tails to sell?! Hah...haha!! That changes things COMPLETELY.]

Y-Yeah!! Yes, it is just a real nice fake! I am a human. Like you. ...Enjoying human things. Eh...ehehe. How...um, h-how do you do, fellow human?

[Nailed it.]
