The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at the Trope Launch Pad.
Breast Expansion is for characters suddenly finding their breasts enlarged in-universe. I don't believe this counts if it's a matter of art style and not clearly a result of something in the work. So maybe Adaptational Curves? IDK.
I do some cleanup and then I enjoy shows you probably think are cringe.Yeah but the thing is that Meggy has the same voice actor, Lizzie Freeman so I don't know what trope fits.
Confused by your context; links would help here.
- Adaptational Curves usually applies if it was a completely different work; eg Meggy is flat in the book but stacked in the movie.
- Do you mean that she went on vacation and came back with bigger breasts within the same work?
- Or do you mean that the show underwent an art style change which gave her bigger breasts?
I'd bet it's either Fanservice Pack or just Art Shift. I don't know if Port Aurora is a spinoff or the name of a story arc in SMG4, but if it's the latter, Art Shift might be your best bet.
actually Port Aurora is the setting of Sunset Paradise, a SMG 4 spinoff show featuring Meggy.
are you referring to Supermarioglitchy4s Super Mario 64 Bloopers? comparing the images on Characters.Supermarioglitchy4s Super Mario 64 Bloopers SM G4s Gang and Characters.Sunset Paradise it just seems like Art-Shifted Sequel or Art Evolution to me, there really isn't enough of a difference in her proportions to call it Adaptational Curves

So in SMG 4, Meggy has a flat chest. However, when she went on vacation in Port Aurora, Meggy has her breasts upgraded. However, is it because the show has a totally different artstyle, or did the fog magically expanded her assets? Which is the right trope?
