A funny idea when doing this fourth, and final Mermaid-for now: what if Mermaid had a mix of fish traits. Not like how in One Piece, where you can have a 'Clownfish Mermaid' more like 'this mermaid has a sharp sword-like nose, but they're not a swordfish'. Like, imagine if a mermaid had both Blowfish Quills and Shark Teeth? Or octopus tentacles for hair and could shock you like an eel?

IDK, here's a cute mermaid. She, uh, didn't come out the way I wanted her to, but I think she's cute enough. Maybe I'll tweak her next time.
