Kermit, Ms. Piggy, Fozzie, Gonzo, Skeeter, Beauguard, Bunson, Beeker, Dr. Teeth and the Electric Mayham, Rowlf, Muhnamina guy, Ernie, Bert, Elmo, Cookie Monster, the 3 already named Fraggles, a bunch of Muppets from Emmet Otters Jug-Band Christmas.
I think that covers all of the muppets that were there.
