Rocky is a 6-year-old little boy who has a wiggly tooth. He is featured on the 1982 Sesame Street album For the First Time. He sings about his latest development in a song, betting that everyone else probably wished they had a wiggly tooth, too. Although he worries that he will lose it in the sink, it eventually falls out and lands by his feet. He plans to put the tooth under his pillow and wait for a new tooth to grow in his mouth.
