Place the melted butter, sea salt, ranch seasoning, Tajín, cheddar seasoning, caramel sauce, and sprinkles in separate small bowls. Arrange the bowls in the center of the board.
Arrange the Oreos, sour gummy worms, mini peanut butter cups, Whoppers, red licorice bites, Goldfish, pretzels, roasted peanuts, and roasted pistachios (I mixed the peanuts and pistachios together) in separate sections around the board, being sure to separate similar colors.
Serve the popcorn in a big bowl on the side for people to serve themselves, or serve it in individual bowls!
