 Dylan Prescott Pickles (voiced by Tara Strong) is the child of Stuart "Stu" Pickles, an inventor, and Diane "Didi" Pickles (nee Kropotkin), a schoolteacher, and Tommy's younger brother.He is a newborn for much of the series, meaning he rarely partakes in adventures alongside the other babies, and is often seen drooling, crying, or babbling.Because of his young age, Dil cannot understand the babies and the babies can't understand him.
