Tommy's new baby brother Dylan (a.k.a. Dil) has the personality of a typical 3-month old: all id. He wants everything NOW and will do whatever he can to get it. And once he does get it, he won't let go without a fight. In The Rugrats Movie, Dil grabs Angelica's Cynthia doll to set the plot in motion. Then with Dil in the driver's seat, the Rugrats careen away in the Reptar Wagon with Angelica and Spike in hot persuit. Dil will wail unconsolably when frustrated, but he'll immediately stop crying when something else attracts his attention. While his tantrums are often annoying, he has the saving grace of all babies: he's irresistably cute.
