Rugrats - Season 9 Episode 6

As Stu & Didi are trying to find a new babysitter for the Rugrats, Grandpa & Lulu recommends Lulu's grand-niece, Taffy (Amanda Bynes). After they see Taffy perform with her band, ""The Saltwaters"", at a bowling alley, they hire her on a trial basis. As she babysits, Taffy teaches the Rugrats a thing or two about music, while trying to come up with a song for her band to play at their next gig -- a grand opening of a gas station. The trouble is, Taffy isn't that great of a songwriter, while Angelica, as always, is tone deaf. As Taffy does her thing with the ""minis"", the Rugrats' parents, at Betty's insistance, spy to make sure Taffy does a good job. They later find out that Taffy was a good choice as babysitter.
