Lulu is a sweet, fun-loving, adventurous woman, and like Lou, is always up for trying new and exciting things. Lulu does however tend to be forgetful and clumsy, mentioning one time she broke her hip after she lost her reading glasses and went into a water slide (after mistaking it for the way to the bathroom). She and Lou have since then married, making her Stu Pickles and Drew Pickles stepmother, Didi Pickles and Charlotte Pickles stepmother-in-law and Tommy, Dil and Angelica's step-grandmother.
While at first, Stu was a bit hesitant of their relationship, he comes to warm up to her after she helps Lou save Dil from an incident with his giant robot Reptar. In Rugrats In Paris, the movie begins with her and Lou's wedding reception, dancing greatly with Lou. Both sons admit to Lou that they're happy for him, saying they knew Lulu was a great lady as they watch her play with the babies. Lou agrees that she is a keeper, but tells them nobody will replace their mother, Trixie. He says that it's Trixie's love that helped him fall in love again. She and Lou are later seen at the end of the movie, after coming back from their honeymoon, celebrating at Chas and Kira's wedding reception. Both are also seen participating in the cake fight that Angelica started. Lulu has warmly welcomed her new step-grandchildren, as do the babies whom all warm greatly to her and adore her.
Lulu has peach skin, purple-gray hair, and a pair of white eyes with black pupils. She is often shown wearing a blue jacket with matching blue high-heeled sandals, earrings and watch and a yellow dress.
