Goof: In a scene before the babies & Angelica go into Chuckie's body Tommy had something pink stuck in the back of his diaper. But once they go inside the body its gone.
Goof: The Rugrats are scared because Tommy's Aunt (ANT) is coming, and it is established that she is a relative of Grandpa. However, when the Aunt shows up, she looks exactly like Angelica. Angelica is an exact replica of HER mother, yet the Aunt is on Angelica's FATHER's side. How did that happen?
Goof: The aunt gets to sleep in grandpa's room. When the aunt is preparing to go to bed, she takes off her wig and places it on top of the bowling trophy. And then she walks out of the room to go to the bathroom. When Tommy and Chuckie walk in shortly after that, when they're about to walk in, they show the room from Tommy's view. But if you look at the desk where the bowling trophy is, the wig isn't there.
Goof: In "Aunt Miriam", Aunt Miriam's meat changes from the first shot. After a couple of shots, the meat disappears.
Angelica: Has anyone ever been inside a dog before?
Tommy: (As the seed starts to grow) Angelica, see what you did?!
Angelica: And I'm glad! (Laughs evilly)
Tommy: Yeah, well, you won't be if Chuckie's tummy explodes while you're inside it.
Angelica: Uh-oh. I never thought of that. We gotta get outta here!
Villain in movie: Yes, yes, all goes according to plan. We'll go inside the President's body, all right. But little do they know that I'm not gonna get the device; I'm gonna detonate it! Ha-ha-ha-ha-ha!
Angelica: It'll grow bigger... and bigger... and then... kaboom! Heh-heh-heh-heh-heh!
Tommy: We gotta get that seed out of you.
Chuckie: But how?
Tommy: Well, maybe you could throw up.
