Every picture of her's copyright was written as "©MARZA Animation Planet Inc" though, not "©SEGA"
SEGA SAMMY do own Marza Animation Planet but Lah, Uh, and Su are characters under the Marza Branch of SEGA SAMMY and not part of the Sonic IP.
"Night of Werewolf" short movie was a colab between SEGA and Marza but since Marza didn't have exciting own characters at that time, they create new ones (Lah, Uh, and Su).
Just like Street Fighter EX series which some characters were belong to Capcom and some belong to Arika.
Most characters from Arika's fighting game "Fighting EX Layer" were debuted in Street Fighter EX.
Well, I imagine it take s alot of effort and money to make an animation and they can't simply make Halloween animations every year.
Yes, it's definitely need snow-themed stage.
Christmas doesn't feel complete without snow, although to be honest I never feel what snow is like nor see it directly since I live in a tropical country.
I've only seen snow sometime, but it's a rare occasion. Even during Winter. I've never had a white christmas before.
One of my fondest memories, in my old hometown, was waking up and seeing it covered in snow. While I have had a few snow days before, I have never seen such thick snow before.
Still, there was no announcement of cancelled school, so I still had to go. I arrived there and met my best mate as we head for school assembly.
As we sat in the assembly hall, the teachers were talking amongst themselves. They decided that even with the students now attending (or maybe not enough students could attend? There were lots but I doubt was the entire school), they decided to cancel school for the day.
Like the rest of the school, everyone quickly got to their feet except for me and I held my friend back. I said "Hold on, just wait." Because I knew that a whole assembly of students eager to have the day off would just cram the doors and me and my friend waited for the crowed to thin out before we left.
Instead of going straight home, we did what we usually did after school, go to the local library to enjoy some internet time.
That was years a go. I now live at the coast where snow days are less likely.
