Have you stopped scrolling once you realized that? The article acknowledges that, and even has a special category of movies named after characters with just a single title drop.
That said, Barbie is a funny case indeed, as it's named after about half of its characters :P
Yes, but it would've been much more interesting to read about title drops where this is not the case. The top titledrops listed that are not names of a character are all names of something else, like locations or objects.
