Two odd-looking, but apparently female,
Muppets. They sing the background vocals on the Muppets' version of the song "
Mahna Mahna". They don't seem to particularly like working with
Mahna Mahna himself, due to his wacky improvisations. As a result, the Snowths come off as serious and somewhat arrogant. This despite the fact that their lyrics consist soley of variations on the word 'doo'.
The Snowths were performed by Frank Oz, one on each hand. That explans why their arms hang limp at their sides.
