The Snerfs
From Muppet Wiki
Snerf was a monster created during Jim Henson's early years on television variety shows. It is essentially a little fuzzy tube with eyes and hair, who pops up and down. When Ideal Toys created the first licensed Muppet dolls, the three characters they chose were Kermit, Rowlf and Snerf. However, there's no evidence that the Snerf puppet was actually manufactured and sold.
After a while, multiple copies of the monster appeared at the same time, and they became "the Snerfs".
They appeared in an early episode of Sesame Street, helping Kermit demonstrate "tall" and "short."
A chorus of Snerfs performed the opening number, "In a Little Spanish Town", in The Muppet Show Episode 113.
Four Snerfs appeared in The Great Santa Claus Switch. One of them appeared in a song as "Snickery".
Originally, The Snerfs had round noses. In The Great Santa Claus Switch, they had beaks. On The Muppet Show, they had trumpets for noses.
