American Greetings have released several sets of Muppet Christmas ornaments since 1993. In 1993, the company issued three Muppet Christmas Ornaments. Two were figural representations of Kermit the Frog and Miss Piggy (with Foo-Foo). The third was a satin ball with Kermit, Piggy, Fozzie, Gonzo, Animal and Rowlf. In 2006, as part of Kermit's 50th Anniversary celebration, five additional ornaments were released, three of which were mini-ornaments that came together in a set.
