Which movie features the birth of Dil Pickles?

The movie featuring the birth of Dil Pickles is The Rugrats Movie.

Released in 1998, the film begins with Didi Pickles pregnant with her second child. She gives birth unexpectedly early to Dil, Tommy Pickles’s baby brother. Dil’s arrival drives the story: Tommy struggles with jealousy and responsibility while the other babies find his constant crying difficult to handle.

The plot soon turns into an adventure when Tommy, Chuckie, Phil, and Lil take Dil away in Stu’s Reptar Wagon. The wagon crashes in the woods, leaving the babies lost and pursued by escaped circus monkeys and a wolf. Angelica also joins the search after her Cynthia doll disappears with them.

A common mix-up is Rugrats in Paris, which introduces Kimi Finster and Kira Finster, or Rugrats Go Wild, the crossover with The Wild Thornberrys. The Rugrats Movie is the first feature film in the franchise and the story that introduces Dil.
