Do you have a story for giving out treats/tricks or do you just use a simple reply/graphic?I have used 2 this year. As I hadn't made a story to go with my greeter costume this year when I got my first few treaters so reused galinda from last year:

The door opened and a pup dressed up as galinda from wicked answered "it's good to see me isnt it! Oh that is the most wonderodious costume I have ever seen! Here you go" she dropped some candy into their bag "Happy halloween!" Then she did a dramatic twirl and closes the door
This is my current story greeter but I customise it a bit depending on the trick or treater like a pet dressed as a witch my witch will assume she is also a real witch and not a costume so I love your costume becomes ah I see you are a fellow witch. And other small changes:

A young woman who appeared to be a witch opened the door. She had an apron stained with chocolate and her hair was a mess under her hat and her house smelt of freshly baked pies. "Hello dearie happy Halloween. I love your costume I bet it took you a long time to make. Here you go take a bag" she said pointing to a pile of little bags of sweets by the door. "Stay safe my dear" she said with a smile "oh and close the door on your way out!" she turned back to the pot on the fire which was bubbling over she whispered something and it seemed to stopped bubbling. She nodded to herself and turned back and shoo'ed the youngster out the door with a wave of her paw and went back to muttering what sound like incantations
I also do a thanks for the treat message from my pup which also changes if the gifter has a treat message to make it a reply to their greeter story:
Pet's name: Daphne Blake
"Jinkies! Thank you so much! Happy halloween" Sarah said smiling "this is such a great treat my brother will be so jealous" then she turned around and ran down the street to the next house.
