|First:||Acorn Nutts and Diapey Butts|
She met Grandpa Lou when he broke his leg during a dance at a retirement home. However, they actually had met years earlier in Europe in 1942, when Lou was a soldier, and Lulu was a singer for the soliders. She had a lovely voice but had the worse memory with the lyrics, much to the constant annoyance of the other soliders (some of whom had to shout the lyrics to her). Lou wanting to get her attentions, cooked her a meal since he was also the cook their. But before Lulu could thank him, the shy Lou ran off. Realizing its her, Lou asks her to sing another one. But some things never change as Lulu sang sweetly but once again couldn't remember the lyrics to the song. She and Lou quickly fell in love. Lulu is a sweet, fun-loving, adventerous 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 and Drew's step-mother and step-grandmother to Angelica, Tommy, and Dil. While at first Stu was a bit hestiant 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, 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 that they knew Lulu was a great lady. 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 partcipating in the cake fight that Angelica started. Lulu has warmly welcomed her new grandchildren, as do the babies whom all warm greatly to her and adore her.
