Pachalafaka--a Turkish Tourist (Hashim) in a Turkish landscape sings as a belly dancer dances around him. At the end of the sketch the belly dancer reveales facial hair (and I think fangs) under her veil.
I'm not sure if Feelings was ever on SS, but there were a few parodies (like the cartoon "Felines").
The middle expression of Gobo's song is "A bird in need is a friend indeed", and I don't get it either. He sings it at first to Boober and Wembley and is soon joined by a group of fraggles (including a few musicians in what looks like African tribe clothing, but more "fragglish". During the second half of the song Gobo climbs a tall stalacmite (and can't get down by the end of the song).
Pass That Peace Pipe is from the Liza Minelli episode (UK Spot), an episode where many characters are getting shot or stabbed (it's a murder mystery show). The number is on stage, but with no scenery. Four dogs sing it: Baskerville (Nelson), an ugly yellow hound (Hunt), Muppy (Goelz, with plastic Muppet eyes), and an Irish Wolfhound (Whitmire) in sunglasses and tropical shirt. At the end of the song each one gets struck by a tomahawk or arrow (Animal even ends up with an ax to the head at the end!).
