Hidden Details: Europe Trip

Welcome to the eighty-third 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 NO JoJo reference. Bonus panels don't count.

1: You're correct Zach! He's hard to spot, but Balthazar in the first panel, outside.
2: The group is being followed by a Lycan. Wolf is looking at him with some interest, being a wolf himself. That was the reference I was going for, but I'll count yours, Erin.
3: Sephiroth is cold because he refuses to wear clothes because he wants to show off his abs. Correct, Cameron Devera.
4: There's a little bag of 800 Lei (the Romanian currency used in Village) in the first panel and Wario is indeed stealing it, Zanreo.
5: Squirtle is indeed still learning about cooking, UltaKi. And yes, he's reading a cookbook called "The Duke's Kitchen - Traditional Romanian Cuisine", which is a reference to the Duke making you food if you bring him ingredients in Village, Flack Jacket.
6: Richter is not comfortable at all while visiting a vampire-ruled castle. I guess it's obvious why, Trigger.
7: Yes Tejayes! Wolf is carrying a Pokémon Snap camera. Good eye.
8: The Duke has set up a little souvenir shop in the castle
9: Among the souvenirs he is selling is a Goat of Warding, as found in Village.
10: And he's also selling shirts with various memes/references on them. Glad you noticed, Marwan Abunura.
11: Wario seems to have bought the I <3 Romania shirt, as he's indeed wearing it in the final panel, CrazySeanDX.
12: They indeed seem to have preserved Luigi's severed hands, Put 9-Volt In Smash Bros Please. I don't know how they did this, but I included it so I have an explanation in case I need them reattached later, when making a comic that involves Luigi using his hands.
13: And yes, there's a little Loss on Samus' drink, Luke.
14: The bus the gang took to return home is Cappn's bus as it appears (as an Assist Trophy) in Ultimate!
15: Isabelle switches from winter to summer outfit. Good catch, John Hattan.
16: And lastly: yes, Luigi getting his hands cut off is definitely a reference to Ethan/Village, Phloxiana.

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