Rubber Band Men

From Muppet Wiki

The Rubber Band Men backed up Lynda Carter in Episode 419 of The Muppet Show on "Rubber Band Man."

The band consists of two types of Muppets as pictured. The first are made almost entirely of a rubber band with hands to strum itself and eyes and legs.

The second are a slinky-like stretchy character with eyes and large lips. They appeared years later on backup vocals for Garth Brooks in episode 102 of Muppets Tonight for a cover of Tom Jones' "It's Not Unusual."
