Yeah, I don't know. Sorry.
This one goes out to Dob and Momes from Crossweird, a crossword stream I've been watching for the past few months. Something they've been doing recently is solving hard puzzles with the help of chat, after using this tool to remove all the across clues, leaving them with only downs... and then using it again to replace about a third of the words with "turtle". So I got the idea in my head of constructing a puzzle where the word turtle really does appear in each down clue at least once. I think it's a fun idea because most people do the acrosses first, so hiding a gimmick in the downs feels like a punchline.
Yes, obviously, I would have LOVED to call this puzzle "Turtles All the Way Down". God, what a good title. I'm actually a little angry with myself that I'm not using it. Unfortunately, it makes the joke a little obvious. I don't want to mention turtles in the title directly because I'm afraid of the jig being up when you read your first down clue. By only alluding to turtles (I checked, you can find them at the bay) I hope it'll take at least two :3
