Sakana is just fish in Japanese, but I doubt Sparrow even knows that

Sparrow had decided today was Sakana's day to do the things. One kid wanted splishes, the other pirate knowledge, now what would this child ask of her? She brought the boy out to the beach without even a collar or a leash and looked around for a while. Borders were clear, other pups were locked up, et cetera. She turned now to her son. "Okay, today is all yours, so what are we gonna do?"

This was by far the smallest kid and all that, so she wasn't sure how he'd take to being alone, but she figured he deserved the attention anyway.
