The Dingers are a species of Sesame Street characters. They are very similar to Honkers, except that instead of communicating by honking their noses, they ring the bells on their heads to speak.
A few songs have focused on the Dingers and their unique talent, including "The Ding-Along Song" and "The Honker-Duckie-Dinger Jamboree" (Martin P. Robinson performed the Dinger in the latter).
An episode featured a Ding-Along; and in Elmo impersonated a Dinger for an impromptu Honker-Duckie-Dinger Jamboree.
There are at least four different Dinger puppets:
Gold with orange nose and hair
Yellow with yellow hair and blue nose
A baby Dinger, with light yellow fur and pink nose and pink curly hair.
