Ahh yes, Halloween. I wasn't a Touhou character in general, but I had a scythe and dark robes to make me look like some sort of death god. I basically shouted out things related to Touhou, such as:
"The Yama will be displeased!"
"If you don't want that candy, I'll donate it to Reimu. I'm sure she'll love it."
"You don't want ME to judge you? I'll let the Yama take care of that."
"Now now, don't be a Yuyuko with that candy."
"Are you Parsee (yes, I think its an actual term) of how much candy I have?"
Other than that, just your normal Halloween. Some jump-scares here and there, but nothing legitimately scary.
