Inside Out delves into many other mind besides Riley's throughout the movie. We get to see what goes on inside her parents, other kids, and even a random bus driver. But other than Riley, every other character's emotions are tied to their outward appearance and gender. It's obviously a visual storytelling tool so we don't get confused whose head we are in, but if this is the case why don't Riley's emotions look like her? Does this mean Riley's emotions are the standard/most important emotions in this universe?? Does no one else in this world have any emotions that don't align with their looks or gender? Are we seeing into the head of the Second Coming?
2. Why did Riley imagine Bing Bong as a train riding hobo?
Bing Bong was Riley's imaginary friend, which means she designed his appearance herself. And at a very young age for that matter. So why the hell would an 11 year old girl in 2015 pick a look that is a clear reference to train-riding hobos in classic Hollywood films from the beginning of the 20th century? Unless Riley's dad is an old Hollywood film-buff, there's no reason for Riley to be familiar with the way hobos dressed over a 100 years ago. And even if she was, why would she want her best friend to be one?!
3. Why did no one notice Bing Bong is basically Koos a la goopa goop from Dexter's Laboratory?
Ok, I get that everyone fell in love with Bing Bong, but how is no one talking about the fact that he is pretty much an exact copy of Dee Dee's imaginary friend in Dexter's Laboratory? Not only are both of them chubby elephant-like creatures with pinkish hues, but they both sound a lot a like, with Richard Kind dubbing Bing Bong very similarly to Dom Deluise, who voiced Koos a la goopa goop on Dexter's Laboratory.
If everything we dream at night is actually being filmed in the dream production studio, that would have some pretty disturbing implications. People older than Riley obviously have some more...adult themed dreams, so at one point dream productions would have to get into straight up porn. Not only that, but dreams often get pretty insane. Just think of the day when dream productions would have to film a scene in which a giant version of Riley's dad is dancing naked with leprechauns while Hitler is in the corner peeing on Bing Bong or something.
