After Ralph Wiggum's is rejected during his audition for the contest, Clarissa (as #17) goes up next to sing. During her performance, she sings a soulful version of "Hush, Little Baby" (a song that Lisa originally intended to sing), much to the delight of the entire audience. After Krusty picks her as the first contestant, Lisa doubts her chances of winning.
When the Li'l Starmaker competition is down to three finalists, Krusty picks Clarissa as the next contestant to be eliminated, making her cry. Krusty pretends to comfort her by telling her not to cry, but tells her under his breath to keep crying in an attempt to boost ratings.
- Aside from singing "Hush, Little Baby" and crying when eliminated, Clarissa has no actual lines.
- The actress that does her voice was the winner of a season in American Idol.
