You can’t confuse them. What do they have in common? I haven't seen any similarities. (At least it’s not easy to confuse them.) But Baltazar and Kaspar can be confused.
I will quote the answer from the previous message!
They are perceived as one person, just with slightly different drawing styles (or after drinking different alcoholic beverages).
"or after drinking different alcoholic beverages" – this is the main point, in my opinion!
To that, I can only quote a famous phrase by Comrade Shpak:
- You need to eat something! (literally: "You need to snack!")
Compare!
On the left - Kaspar, and on the right - Baltazar (in my vision)
On the left - Ravenna, and on the right - Zoltan
