Sarah "Taffy" Maynston 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. 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).
- Taffy doesn't appear in the series until the eighth season, and thus only appears in a few episodes.
- She's not a character in All Grown Up!, but she'd be around twenty-six on the show if she had been a character. By the spin-off series, the Rugrats are in middle school and don't really need a babysitter anymore.
- Strangely ironic! Taffy's voice actress, Amanda Bynes, did the voice of one of Charlotte's daughters, Nellie from Charlotte's Web 2: Wilbur's Great Adventure. Whilst Taffy's grand Aunt, Lulu Pickles, was voiced by Debbie Reynolds, who provided the voice for Charlotte in the original 1973 Charlotte's Web film.
