NPCs will be in scary costumes for Halloween, and and dressed in warm clothes for Christmas
This would go great with my idea of the thematic change grass and leaves in this suggestion:

I won’t give any examples because I’m bad at creativity
If you’re too lazy to come up with ideas yourself, create a competition for the community, it would be interesting
P.S. this only applies to the regular version of NPCs (not the shimmer)
