Please only comment with ONE hidden detail or reference!

There is one Loss, one Balthazar and one crewmate. Bonus panels don't count.

1: Dog (and duck) are wondering if Tarountula is a tennis ball in the first panel. You can't blame him, The Negotiator.
2: A Hoppip apparently stole Daisy's daisy sunglasses from the previous bonus comic. I think it looks good on them, Brayan. And as mentioned by C2123, Kirby is the only one who notices this, though.
3: Alolan Exeggutor makes another appearance. He's visible in the background of the second panel. Glad you noticed him, Generic Hero.
4: This week's crewmate is visible in the window in the lighthouse in the third frame, as discovered by Phloxiana.
5: Dog is clearly excited about being a Pokémon in the third panel. His tail is wagging rapidly!
6: The question mark appearing above Lechonk in the fourth panel is the same one that appears above wild Pokémon in the actual games.
7: Balthazar/Baltabun is looking down from the lighthouse in the fifth panel like the king he is. Glad you noticed this very tiny appearance of him, Andrew Hammond!
8: Someone carved a "Dicklett" into the cell wall. My sense of humor is very mature, Percylegallois.
9: Someone also played tic tac toe on the cell wall, but they used a triangle and a square too, making it look like a PlayStation-themed version of the game, as pointed out by Trigger.
10: I think I've done a loss in tally marks in a prison before, so this week I decided to make the collection of tally marks form one big loss. Just to keep things fresh. Good catch, Cameron Devera.
11: Not a clue what you're talking about, Spirit of Gotham. Vaporeon? I just see the words "Hey guys, did you know that-" on the prison wall.
12: Duck is mad at Dog in the final panel, since Dog is the one who caused them to end up in prison. Can't blame him, Fighting Master.
13: Apparently, there's a prison in the lighthouse building on Poco Path. I haven't encountered a prison in this game yet so I just looked for a building that could function as one and this seemed like a good spot since there'd be some space left next to the lab.
14: I did not know this: apparently there are no Swimmer trainer classes in Scarlet/Violet, making Luigi's remark to Daisy a bit ironic. Thanks for informing me, Edgar Castro!
15: Another one I hadn't even noticed myself: Snarl and Crunch are both Pokémon moves! I hadn't intended that, but you're absolutely right, Lord Circe.
16: Calvin Barbanell pointed out a coloring mistake one of the interns made: Sora's shoe is missing some white in the third panel.

Next week around this time, I'll reveal all the details. The ones that have not been found will be marked italic.
