Hidden Details: Everyone is... Suddenly Into Fitness?

Welcome to the seventy-first episode of the Hidden Details blog!

Have you found some obscure reference or detail in this comic? A JoJo reference? A sneaky little Loss? A callback to a previous comic? Let us know what you've found in the comments! Every detail that has been found will be added to the list below. Once everything has been found, this comic will officially be marked with "all details found".

Please only comment with ONE hidden detail or reference! Bonus panels are not counted.

There is ONE Loss, ONE Balthazar, and NO JoJo reference.

1 - On the wall in the first two panels, there are two motivational signs telling the fighters to not wait for buffs, but BE the buffs.
2 - That's right Anreo, Simon is using his Vampire Killer as a jumping rope.
3 - And yes, he is indeed drinking some Holy Water/Gatorade mix, Diego Gzz. Wonder what it tastes like.
4 - Everyone is dressed in sport outfits based on their original colour schemes.
5 - Sandbag makes an appearance in the second panel, cause how could he not.
6 - And he is indeed one of many, Put 9-Volt In Smash Bros Please. A bunch of "dead" Sandbags are piled up in the back.
7 - The speed bag Little Mac is using seems to be Sandbag's little brother. Good catch, Jonathan Stein.
8 - And you're right, John Hattan. Terry donned his Fitness Fury cap instead of his Fatal Fury one.
9 - Link's stamina gauge (from Breath of the Wild and Skyward Sword, kinda) is indeed visible while he's running on the treadmill, Eli Hurtt.
10 - Sonic's treadmill is breaking down as it can't handle his speed.
11 - The sign behind Sonic and Link says Falcon/Warlock punching is forbidden. And yeah, you can guess why, Trigger.
12 - Fox is checking out his buns in the mirror. I was unaware of any buffs to Fox/Wolf's butt in Ultimate, but I do know he used to have buns of steel in Brawl.
13 - The Purple Pikmin are sitting on Captain Falcon's bar because they weigh a lot. You're reading too much into it, UltaKi, but I'll count it ;)
14 - The weights on Captain Falcon's bar indeed have the Smash logos, Luke.
15 - And yep, Falcon's knee is bruised from all the Falcon Knees he's been dealing out, Zach.
16 - The Pikachu symbol on the door in the fifth panel indicates it's a Pokémon toilet.
17 - Yes, Julia, Donkey Kong is repping some sweet Balthazar-themed sportswear!
18 - And Chrom is once again wearing something that is missing a right sleeve to show off his sweet bicep and/or Mark of the Exalt.
19 - Haha yeah, that's me adding loss last minute, Diego Gzz. It's on the wall behind Donkey Kong, with a sarcastic 'ha ha funny' written underneath it. You already mentioned the Gatorade so I won't count this one though.
20 - Waluigi's LOSER graffiti makes another appearance, after the one in the Sephibutt comic. Good catch, Very Large Mandarin Slice. Cool name, too.
21 - The final bit of graffiti on the wall is indeed Kirby, Phloxiana.
22 - The bin is all stuffed with banana peels because Donkey Kong needs those bananas for his gains.
23 - And YES! Wario being the one who's jumproping is indeed a reference to one of his idle animations in Wario Land 4, Youmg! So glad you noticed.

This is another one where it's kind of hard to decide what counts as a detail and what doesn't, but I'll just see what you all come up with. I counted at least 20!

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