Now, this one is questionable. I remember reading about it in the inflation movie list(what was that list called?) that used to be on Wren's old site. In Nick Danger: The Case of the Missing Yolk, the main clip of interest was the actually-not-that-great "Booby Chew" clip. Almost as a side note, the description of the movie also mentioned a scene in which "Nurse Bambi's" breasts slowly grow in the background while two characters talked. Well, of course, I scoured the web for it and never came up with anything.
Now, someone has posted the whole movie on YouTube. I believe the clip in question starts at 4:28 here: Case of the Missing Yolk Part 3
Is there B.E? Possibly. I mean, she does look bigger by the end....maybe. Kinda sorta. Could be the angle. I was thinking, "Why would they make the inflation so minimal for a sight gag?" but then I remember what the Booby Chew clip looks like(see Part 4 for that), where their breasts hardly grow at all. Anyway, it was driving me mad all these years, and now I've finally seen it and.....well, I can see why it was just a side note, now.
Hmm...I can't tell the difference if you ask me. It just looks like a different camera angle.
