Twiddlebug ABCs is an animated storybook included as a bonus feature on the Love to Learn DVD from 2016.
A green Twiddlebug hosts the three minute feature, presenting each letter of the alphabet accompanied by a Sesame Street Muppet character.
The illustrations are lightly animated and are originally taken from the 1996 Sesame Street ABCs series of board books, with artwork by Tom Brannon, David Prebenna, Carol Nicklaus, and Maggie Swanson.
They were later reprinted in Big Book of ABCs and 123s under the title "The Twiddlebug Alphabet."
