Please only comment with ONE hidden detail or reference!

There is one Loss, one Balthazar and one crewmate. I count every Maus seperately. Bonus panels don't count.

1: The first Maus was hiding behind Corrin. He's visible in the second panel after Corrin teleported, as found by Daniel Myhre!
2: That is indeed Sir Balth of Zar's coat of arms on Marth's cloak in the first panel, Spirit of Gotham. Couldn't have said it any better myself.
3: The second Maus is having a nice soak in the sink in the third panel.
Marth apparently has his own cup: it says アルス (Marusu/Marth) in katakana. Glad you noticed, Zanreo!
4: This week's loss is visible in the bubbles in the sink in the third panel, as pointed out by A Sad Fat Dragon with No Friends!
5: There's a portrait of Lizzie, George and Ralph from Rampage in the background of the third panel. We're running out of truly obscure characters to hide in the background, Generic Hero.
6: Maus 3: the tail is visible behind the curtain in the third panel. Found by Tejayes.
7: Lucina has a cool little Mark of the Exalt symbol on the back of her phone as seen in the fourth panel, and as pointed out by Cameron Devera.
8: Yeah, I think Samus being strong as fuck is canon, John Leonard. Hence why Roy can't seem to beat her at armwrestling in the fifth panel.
9: Maus 4: hiding in the lamp in the background of the fifth panel. Found by Jared Degear.
10: Toon Link's belt is indeed a little sus in the sixth panel, Lord Circe.
11: Maus 5: chilling on Little Mac's shoulders in the final panel. Found by Fighting Master.
12: Corrin switched from eating a banana to eating an orange in the Somniel. Apparently oranges are very common there, William Dryden.
13: Sommie, the Somniel doggo, seems to be a bit infatuated with Isabelle in the final panel. They'd make a cute couple, Miz Kriss!
14: Yes Jon Brouse! Alear is wearing five Emblem Rings in the final panel, and they all belong to the Fire Emblem characters that are present in the same panel!
15: Ike has received some swimwear in the final panel, which he seems a bit suspicious about. This is A) a reference to the thirsty Fire Emblem Heroes art where all the characters get "Summer" outfits (although I don't think Ike has one), B) a reference to the Somniel having a pool and C) foreshadowing for the bonus comic. I'll give you a point for that one, UnSaxon51.

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