An animated typewriter with eyes and arms, and mobile wheels appeared on Sesame Street beginning in Season 6. The Typewriter would demonstrate letters by typing out the letter, and a word beginning with it, on himself. He often fumbled, which frustrated him. The Typewriter's most notable dialogue, apart from announcing the letter and the word, was his trademark "Noo-nee-noo-nee-noo" sounds. Twenty-six shorts were produced, one for each letter of the alphabet, and continued to appear on Sesame Street as late as Season 35.
