This is a new OC who is heavily inspired by Tim Burton's The Nightmare Before Christmas.
He is Sally and Jack Skellington's son and heir to the pumpkin crown. Except, he doesn't want to be Pumpkin King. Then suddenly Oogie Boogie comes outta nowhere and attacks his parents not knowing they have children so he and his sister run off in two different directions and then he finds a glowing orange lotus flower in the almost colourless environment of Halloween Town. Out of curiosity he touched it ("Wonderful! Curiosity killed the cat you know." Dr. Finkelstein said this to Jack when Jack came to borrow supplies hinting that this is a good phrase amongst the residents of Halloween Town.) and now he is stuck in the same dimension as Lotus Kai and is now the patron of Orange. He can also control fire now.
Also @angelalice noticed that you guys are wanting to name him "Pumpkin" but in different languages and pointed that out to me. I'm not being racist or anything but I don't want to do that since its kinda like naming a human being Bungo. (Tagalog for "Skull")
