A series of animated inserts, produced in 2008 for Sesame Street English, featuring an animated version of Cookie Monster (voiced by David Rudman) and an animated version of Elmo (voiced by Kevin Clash) singing about the various sounds different letters make. The segments appeared on Sesame Street in Season 40, with some subsequent editions premiering in following seasons.
The animation was designed by Superdeux and animated by Peter Belsky. The songs were written by Cathi Rosenberg-Turow and Russell Velázquez. International versions of the segments were produced for Plaza Sésamo, Shalom Sesame, Galli Galli Sim Sim and Iftah Ya Simsim. The inserts were later put on the streaming service Showmax in South Africa, under the title "Sesame Street ABC's".
