Supercell has been kind enough to offer their new emoji's to the fan forum community for use. You can find these emoji's under the "smiley" icon in the toolbar. Note that they are quite a bit larger than the usual smiley size and that in order to be able to see them for selection (when replying to a thread), you must use the full "Reply" tab on the top right of a post. Hit that tab prior to constructing your post.
