The horn glows in the dark. It was made from two things. A purple christmas icicle and glow in the dark hot glue. Took a long while to mold out but turned out to be fairly light weight and sturdy. I made a new one that has EL Strip tube light wrapped around and then sealed in with hot glue. I kept a little pocket under the mane to store the battery pack. I can't wait to show you guys! Thanks for the favorites and enjoy!
