There is TWO Losses, ONE Balthazar and TWO crewmates (intern added a Loss and a crewmate without informing me). Bonus panels don't count.

1: Rosalina is directing a Luma to the top of the Christmas tree in the first panel so it can function as a nice ornament. Glad you noticed, Zanreo!
2: Balthazar is represented as a tree ornament in the first panel, as pointed out by Generic Hero! When I asked my intern what he thought it was, he replied "dog."
3: That cedar tree is straight from Animal Crossing by the way.
4: Wait, what? Did I do the "Pikachu testing Christmas lights" thing before, Edgar Castro? I can't even remember.
5: Seems like Piranha Plant wants to be a Christmas tree in the first panel as well, Lord Circe!
6: Min Min is using her long arms to put up Christmas decorations in the same panel!
7: Everyone is either sleeping or drowsy, because Jigglypuff is part of the choir in the second panel. Not a great choice to have her as a singer. Good catch, VisionPlayer22.
8: I made sure to make the rest of the choir mute characters as well, as mentioned by Musical Icarus. Even if they would be awake, I don't think they'd make much sound.
9: Yes, the retro characters are still a thing, Calvin Barsbanell. This time it's the angel from Messiah (2000), from which the Roblox Oof! sound originated.
10: Bowser is apparently something of a tailor, indicated by the specs and the measuring tape in the third panel, as mentioned by LadyValerie!
11: Isabelle is using a SusBook in the third panel, as mentioned by Cameron Devera.
12: And yes, she's also using the Nookle search engine, Trigger. It's a lot more popular than the more privacy-focused NookNookGo.
13: Apparently, my intern put a loss on Thors's belly in the fourth panel, as found by Spirit of Gotham. I was not aware of this until Discord members pointed it out.
14: Same goes for a crewmate among his tattoos in panel six. Good catch, Tyce Joubert.
15: The "real" Loss, however, is in the snowflakes in the fourth panel, next to the R!
