(1) Threw the entire The Rugrats Movie, Lil's socks where blue! But they where originally pink, to show the difference between Phil & Lil!
(2) Phil usually doesn't have ear lobes, unlike Lil, but like the other babies, in this movie, and other episodes, Phil has ear lobes!
(3) We all know Tommy's slogan is "A Baby's Gotta Do What A Babies Gotta Do!", but in one scene, the reptar wagon says Tommy's slogan! But his dad records everything Reptar says, how was he to know this slogan if the babies don't talk?
(4) If you notice in every episode before the Rugrats Movie, the babies use the word diapers correctly, but as of this movie, they say diapies instead of diaper! Have the babies grown less smarter? But Angelica still says diaper though, as heard in episodes after this movie. The creators of the movie know of this mistake and say they meant to do that, because the babies where to advanced in words at that age, and it'd be hard to believe they are babies if they say words correctly.
I can't believe they created this movie with mistakes like that passing by! Speacially #3 & #1!
