Beginning in late 2011, a member by the username of Muppetboy09 started to create his own smiles of various characters from different Muppet productions, influenced by the original smilies made by James Caroll. Only a few months later, CaseytheMuppet started making his own smilies, and from there, it stemed into a variety of members creating a wide range of muppet and Henson smilies. All are permitted for use in MC forum posts. To use these as smilies, right click the image, copy the image URL, and in the reply box on a thread, click the icon that looks like a picture of a tree. Paste the URL into the popup.
