Please only comment with ONE hidden detail or reference!

There ONE Loss, ONE Balthazar, and NO JoJo reference. Bonus panels don't count.

1: No worries Cherry, this is absolutely a hidden detail. I went out of my way to count the hidden 1-Up Mushrooms and I made sure to draw the 7th one you encounter in the original Super Mario Bros. Shame I miscounted and I should have used the 8th one, but oh well...
2: And Lakitu is indeed present in that level, Dirtydan8991! He is practicing one of his many part-time jobs, in this case "annoying video game antagonist". He drops a spiny shell on Incineroar and his bandage is visible in the next panel.
3: In the same panel, one can spot the same realistic Lucas drawing as a few comics back. Good eye, Erin.
4: Kirby has indeed taken up his doctor's outfit. I'm not sure if he had to swallow Dr. Mario for that, because it's kind of weird that he had to swallow a corpse, but you're right nonetheless, Zach.
5: Yoshi is the nurse assisting doctor Kirby. Good catch, Zanreo.
6: There's a sign indicating where the Mushroom Kingdom characters go. Seems like they've been busy sorting all the dead fighters.
7: In the final panel, there's a little Mr. Game & Watch bookend visible on the shelf. Nicely found, Trigger.
8: And the bottles on the floor in this panel indeed form loss Emma Medals! Glad you found him this week!
9: Incineroar and Kazuya wrote "B <3 M" on Bowser. This, of course, stands for Bowser <3 Mario. But you knew that, John Hattan.
10: I can't tell who was earlier because Patreon doesn't show exact timestamps, but both PLANTMAN and Cameron Devera mentioned the Kazuya dickbutt on Bowser at the same time.
11: The underside of Bowser's feed has been changed into a Minion by Kazuya and Incineroar. I was quite proud of my creative design choice here, Luke.
12: The beer bottle in the final panel shows Balthazar. It's Balta Beer, getchell_. If I ever brew my own beer, that's what I'll call it.
13: The wines in the final panel spell Vin and Diesel. Kind of reflecting the meme that was popular this week, but also just a play on vin meaning wine. Glad you noticed, Dominic Caruso.
14: Daisy's bra indeed has daisies on it, CSDX!
15: And my man Luigi, who seems thrilled at the fact that he must have had a threesome, has "Love machine" written on his hat. I wonder how disappointed he must have been when they revealed it to be a prank, Jonathan Stein.
16: Once again, I can't tell who was first, but both Carrick RaccoonBro Inabnett and Matthew Miller noticed Wario's belly button piggy doodle.
17: Wario is indeed wearing sexy heels, Put 9-Volt In Smash Bros Please. They are Peach's heels, actually!
18: The "cool S" is drawn on Wario. People who are young at heart like to draw that S all over the place, as I'm sure you know, lillbro64.
19: Mario is indeed wearing the outfit he was wearing when he died, Gavin Walker. I messed up his outfit in the previous comic.
20: And finally, yes, the flaming wheelbarrow makes another appearance, Jackofspades626!

After one week, I'll reveal all the details that haven't been found. These ones are written in italic.
