Lulu Plummer is one of Julie Plummer's children of the 2005 action comedy film, The Pacifier. She is the middle child of the Plummer family and is the most troublesome of the five. She also belongs to a troop called "Fireflies", who are bullied by another troop called the Bear troop but in the end they beat the Bear troop boys up for being so mean to the girls.
Lulu is kind of mischievous to Shane Wolfe, and asks him lots of questions. One night, when she follows him down the hall, she asks him "why his boobs are so big", but he tells her that they are not boobs.
When Lulu walks into the playroom with Shane, she asks him if her boobs will get as big as his someday. However, he replies with "I think it's time you went nappy-poo in beddy-bye land". His words greatly embarrass Lulu.
With that Lulu storms off to her room, declaring, "Disrespectful. And I think I was interested in you!"
