Phil and Lil DeVille

Phillip "Phil" Richard Bill and Lillian "Lil" Marie Jill DeVille are the twins from the Nickelodeon shows Rugrats and All Grown Up!, and are among the series' original characters.

Phil and Lil are voiced by Kath Soucie, who also does the voice of their mother Betty.

In Rugrats
Phil and Lil are twins who are alike in every possible way. They were even dressed to match: They both wore pink and purple-striped shirts, and overalls with a polka-dotted handkerchief on the left side and a duck on the right, and both had a small amount of brown hair on top of their oddly-shaped heads. Phil wore blue shoes and shorts with white socks, and was drawn (for the most part) without ear lobes (episodes from 1996 to early 1999 and The Rugrats Movie show Phil with ear lobes). Lil wore pink shoes with orange socks, a pink bow on her hair and no shorts (exposing her diapers like Tommy Pickles), and was always drawn with ear lobes.

They also shared the same interest: consuming worms (which they have often called "Chocolate Spaghetti") and toilet water. They often used their "full" names, Phillip and Lillian, especially when arguing. Their parents Betty and Howard often confused the two, despite permanent differences like the ears, as well as of course their sexes. Lil is 2 minutes older than Phil.

In All Grown Up!
Before All Grown Up!, a few Rugrats stories touched on attempts to either differentiate the twins personality-wise ("Twins Pique", 1993), or physically separate them ("Together at Last", 1992).

However, separating the twins only got serious in the new spin-off. Its premiere, "Coup DeVille" (first US tx: April 12, 2003), was focused on the twins. Lil strongly retaliated at being paired with Phil on a science project, as well as being treated "like a single package" with Phil, and even refused a trip to Twins Canyon with her family on that principle. This episode also repeated the "Lil is older" fact from the original series, and also revealed Lil to have an even longer name than was previously let on: Lillian Marie Jill DeVille. Lil moved to a separate bedroom in this episode.

Since then, the twins have evolved distinctly different personalities. Phil still enjoys repulsive objects (although he is beyond eating worms and insects, he once won a science fair by growing mold on cheese and socks), and has been referred to as "socially inept", while Lil is beginning to find interest in boys and become more social, and she has also picked up an interest in sports, in particular soccer.

Referencing their baby days when their favorite thing was to eat worms, Phil & Lil's favorite food in All Grown Up is Spaghetti.

In the episode Susie Goes Bad Lite, it is revealed that Phil is a good cook.

A new look
In season two of All Grown Up!, all the characters got new looks. In the second season, Phil was presented as being more "decent" when it came to apparel and his hair. In the first season, his hair was messy and always wore a t-shirt under a collared shirt with green cargo pants. Soon after, he began to sport more outfits, such as jackets and other variations of collared shirts with blue jeans. His hair was neater too. It was drastically similar to Lil's hair, only his was a bit shorter and had more of a part in the middle. Lil and Kimi both received new hairdos. Lil's hairdo was similar to one the title character of As Told By Ginger wore in "Foutleys on Ice": straightened out with one streak dyed pink (the color has varied, however). In one particular episode, Lil had Phil dress up like her but when he made her look bad, she donned a pair of pink sunglasses, long blonde wig and a wide brimmed red hat with a feather.
