It's a little late for these two because I was put off by some of the recent changes on the server and I've been lazy but may as well still get them in, they're supposed to be a chocolate coin and a chocolate orange if you can't tell. I'm also too lazy to make it so that you can still flip the chocolate coin and split the chocolate orange into pieces by smacking it against something but oh well.
