Phillip Richard William "Phil" and Lillian Marie Jillian "Lil" Deville are main characters in the Nickelodeon series Rugrats, and its spin-off All Grown Up!, as the tritagonists and minor protagonists of both shows. They are both very close twins, although they often bicker with each other, are are both friends of Tommy and Chuckie. They are voiced by Kath Soucie.
Phil and Lil are the fun and weird babies of the group, as they both like to eat many bugs.
They both care about their parents very much, as well as each other, and they are always there for each other. Even when they fight, they do put aside their differences to work together to help their friends.
They also care about their friends very much, like Tommy and Chuckie, and helps them out in many situations, like helping Chuckie save Tommy and Dil from the monkeys in The Rugrats Movie.
They have many funny moments, like their funny story about starring in a diaper commercial in "Baby Commercial", and when they wore spaghetti on their heads in "Candy Bar Creep Show".
Like Tommy, they also go on adventures that are scary and messy, thinking those are the better adventures, showing bravery and courage.
Kath Soucie did a great job voicing them.
They can be annoying sometimes, mainly when they argue with each other or their friends.
They do have some gross out moments, mainly with their eating bugs habit at times.
They are sadly unlikable sometimes, for example, during "Grandpa’s Bad Bug" and The Rugrats Movie, they were at their worst, as in the former, they along with Tommy and Chuckie, were doing something badly to Grandpa Lou. and in the latter, they had a hatred over Dil and tried to get rid of him
It is revealed in a Nickelodeon magazine that Phil and Lil's birthday is March 31st and that they are 15 months, when Tommy is 1, making them 3 months older than Tommy.
