Hidden Details: The Cat in the Can

Welcome to the eighty-ninth 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!

There ONE Loss, ONE Balthazar, and ONE JoJo reference. Bonus panels don't count.

1: Kazuya did indeed bring his own handcart/wheelbarrow, Cherry. We know it's his because he decorated it with some sweet-ass flames, just like the ones on his pants.
2: There's a KEEP OUT sign on the basement door, probably written by Sakurai. Correct, Cameron Devera.
3: As previously commented, the cans in the basement in the second panel were indeed meant to be Inkling ink cans, but people on Twitter thought they were an Among Us reference. Glad you noticed it, Phloxiana.
4: There's also a box with Trophies in the basement, since they are indeed sitting unused after Smash switched to Spirits (RIP). Good catch, John Hattan.
5: The weekly loss is found in the tallies on the prison wall. You found it this week, Dirtydan8991.
6: There's a ball of yarn in Incineroar's cell, probably to give the big cat something to do. What does Waluigi have to do with a ball of yarn, other than also being purple, Erin?
7: Haha yes, thanks for noticing Trigger! Not only did I put Balthazar in this week's comic, but also Zaza (one of my chickens) and her chicks, since they were born while I was making this comic.
8: As mentioned, Balthazar is there as well, in the sixth panel, to the right. Good catch, Tejayes.
9: Yep, the seventh panel is indeed a reference to the "THE WHAT" meme, CSDX! Weird how no one seemed to notice, huh?

10: Captain Falcon's buns of steel are very clearly visible as a bit of fanservice.
11: Lucas is indeed depicted as a realistic crying boy, Marwan Abunura. It's a parody on those kitschy crying gypsy boy paintings you can get for very cheap:

12: Yeah, the "LOSER" graffiti is becoming a bit of a tradition, huh? You can see it once more on Incineroar's cell wall. Good catch, Luke.
13: Yes!! Incineroar mentions Revenge, which is one of his moves in Smash (and Pokémon)! Glad you noticed, Youmg!

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