The Honkers are unique creatures with honking noses from Sesame Street. The honking sounds are how they communicate. Several Honkers have appeared throughout the series, and they each are different colors. Two of them have been named: Homer Honker (green with blue hair) and Henrietta Honker (small pink "baby").
The Honkers have no consistent performer; whoever happens to be available performs. In one of the Sesame Street films, Tim Gosley performed Homer as a horn for Oscar's car. Some songs that they have performed include: "Honk Around the Clock" and "The Honker, Duckie, Dinger Jamboree".
Sesame Street has also showcased a similar species, The Dingers, who communicate by dinging a bell on their heads.
