Pet adoption Booth
Charlie has an area set up where he has a pen with some young puppies running around in it. He also has a Cat or two in super comfy cat cages. He also has pictures/stories/personalities of all the adoptable pets at the pet store organized in a book, with signs mentioning that they are a perfect present for Christmas. He might swap out with any of the other pet store workers so he can enjoy the festival with his wife at some point.
