Who is Sunny Baudelaire from The Vile Village and what is their importance?

Sunny Baudelaire is the youngest Baudelaire child, depicted as an infant throughout much of the series. Although she is just a baby, who cannot yet walk and who speaks in monosyllabic baby talk, Sunny demonstrates advanced problem solving skills and adult intelligence. She is best known for her four sharp teeth and her biting skills often help the Baudelaires escape from Count Olaf's clutches.
