Jack is a skeleton (obviously) and has sharp fingers, he can pop off his head at any sort of time. Not to scare others of course, but when he feels playful or stressed. Has a suit and pants that fit his size and have white stripes all around on it, along with a bow that looks like a bat to fit the horror and halloween vibe. He's the leader, or as known as the "king of halloween", or "king jack" He is in a relationship with Sally. And he's absolutely kind and actually caring for others despite him being the king of halloween.

Sally is a creation created by the local scientist at the neighborhood. She has pale light blue skin, some stitches around, a dress that has different patches on it all around, white socks and black heel-like shoes. She is in a relationship with Jack. She acts like a mother, being gentle and all, but she can actually be quite protective.
