Taffy

Sarah "Taffy" Maynston (voiced by Amanda Bynes) is Lulu's 16 year old grand-niece (Taffy's maternal grandmother is Lulu's sister), who was hired as a regular babysitter for the babies (or "The Minis" as she calls them) after Didi Pickles decided to go back to college to earn her master's degree in child development. Despite her obviously unorthodox babysitting methods, Taffy's the best babysitter the Rugrats have ever had. Being the lead singer of her band, 'Taffy and The Saltwaters', she also loves to sing and play guitar. She is also a little clumsy. She cares about the environment and also believes in honesty.

Angelica admires Taffy greatly, which makes Taffy ecstatic to have her own "groupie". Taffy, like most teenagers, does go after boys (only seen once in the show).

At one point, the babies believe she hates Dil after they hear her say she hates "Dil Pickles". however, they take it out of context as she is talking about dill pickles. At the end of the episode, the babies are relieved that she doesn't hate Dil and called him 'sweet'. She is also revealed to be fond of dill pickles, saying that its sweet pickles she hates, which is again taken out of context by the babies.
