I don't think you can... I've certainly never seen them.
Just make some out of orange sugarpaste... It'll be SO quick!
roll a ball - slightly flatten the top. Use the back of a knife or a veining tool to make the indents. Then cut in half!!!!
Use fondant, it would probably taste way better than those candies! I hate them! The pumpkins and candy corn are like waxy sugar LOL.
