Lil and her brother Phil are twins who are alike in almost every way possible. Usually dressed to match, they both wear pink with black-pinstripe shirts and turquoise outfits (Phil's being a shirt and Lil's being a dress) with a 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. Lil wore pink shoes, a pink bow on her hair and no shorts (exposing her diaper like Tommy Pickles), and was always drawn with ear lobes. Lil is older than Phil by two minutes. in rugrats in paris the movie they now have dark brown hairs lil wears a pink or purple bow, her shirt is now a darker flamingo pink colour and her dress is green instead of turquoise and has light skin instead of peachish white skin. 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, against one another when arguing. Their parents, Betty and Howard, often confused the two despite permanent differences, like the ears, as well as (of course) their genders. It is often believed in various fan circles that the inspiration for their names may have come from Ayn Rand's book Atlas Shrugged, which features two in-law characters named Phillip Hardride and Lillian Rearden.
