Mermay suggestions? (Patreon)

time to collect prompts for the month of May, and I feel it'd be fun to draw some fishies, so let's use Mermay for a theme!

suggestions can include previous mer designs I've used (betta!Baku, my old mer!strawhats, etc) or you can give me something completely new, as long as 

1. at least one character in the prompt is half-fish
2. some kind idea to work with beyond what character is there as always both sfw and nsfw is fine~
3. one prompt per person please! it's already a (fun) struggle every month to pick through your prompts to make the poll haha
