Riley Andersen

Riley Andersen is a major character in the 2015 Disney/Pixar film Inside Out. She is a 12-year-old girl who loves hockey. She was uprooted from her happy and simple life in Minnesota and taken to San Francisco, California, where she experiences various changes in her life. Her emotions (Joy, Sadness, Fear, Disgust and Anger) help her through this tough time, ensuring her well-being.

Personality
Riley's emotions contribute to her primary behaviors in the film. Overall, Riley is upbeat, honest and goofy when she is content. However, at adolescence, Riley becomes more sentimental and uncertain of herself as her other emotions begin appearing. By the time her family moves to San Francisco, she starts to be more troubled, irked and lonely. Her emotions at this point try to help her get adjusted to the new life. Riley can second-guess herself, but she doesn't always repent her actions.

Riley really misses Minnesota and is unable to cope with the transition. However, Riley fears letting her parents know she's upset since they want her to accept the new home and that she has always been their "happy girl".

As time goes on, however, Riley becomes emotionally vulnerable, entering a sort of apathetic depression and coming to the point where she tries to run away, almost losing herself in the process. But it is here where she realizes that she had almost given up on the things that matter the most to her in life and realizes the risk just in time. Returning home and admitting to her parents that she's greatly depressed, she learns to accept San Francisco when her parents comfort her over the personal loss and Riley (with the guide of her emotions) eventually adapts to her new home.

Physical appearance
Riley is a 12-year-old girl (11 years old prior to the end of the film) with a slender figure and shoulder-length, dirty-blonde hair. Unlike both her parents, she has blonde hair and blue eyes, while both her mom and dad have brown hair and brown eyes. This implies that both the blonde hair and blue eyes are recessive traits. Riley has very faint freckles around her nose. She also has a noticeable gap between her two front teeth.

Riley is seen wearing a different outfit on a daily basis. When first shown in the teaser trailer, she wore a long-sleeved shirt with thin horizontal red, yellow and green zigzag lines, brown pants and red Converse sneakers. When Riley arrived to her first day of school, she wore the same outfit, but with a yellow jacket. When Riley suffered a brain freeze, she wore a solid pink short-sleeved shirt, blue jeans and green Converse sneakers. When arriving at San Francisco, she wore a long-sleeved rainbow shirt, blue jeans and pink socks. Riley's pajamas consisted of a green short-sleeved shirt with blue trim featuring a koala bear on front and dark blue sweatpants.

Mind Locations
Her mind is extremely large, and includes certain locations like:
 * Emotions' Headquarters: The central part of Riley's mind, where Anger, Disgust, Joy, Fear and Sadness all live and control Riley and where her memories are produced.
 * Personality Islands: Seven personifications of different sides of Riley's personality, as determined by the core memories.
 * Long Term Memory: Enormous shelves of various memories forming the main layout of her mind.
 * Imagination Land: A place where everything Riley imagines is built.
 * Dream Productions: Where dreams are filmed.
 * Subconscious: Contains Riley's worst fears.
 * Abstract Thought: A place were ideas (or anyone inside) are simplified to abstract concepts.
 * Train of Thought: A train that connects Headquarters and the rest of the mind.
 * Memory Dump: An abyss surrounding Headquarters, where faded memories end up and eventually disappear to be forgotten forever.

Inside Out
Riley is a major character in the film. Her mind is the main location of it and the main priority of the movie. When Riley is first born, Joy, her first living emotion, is conjured up with baby Riley smiling right at her parents. A few seconds later, another emotion named Sadness appears and makes Riley cry. Joy pushes Sadness out of the way and makes Riley happy again. Over the years, Riley starts to grow up in Minnesota and her other emotions, Disgust, Anger and Fear, are born. Riley becomes happy and jolly pretty much all the time and hardly sad at all. Because of her happiness and joy, Joy unintentionally mistreats Sadness (who was only used when Riley threw tantrums). Riley also becomes one of the best players on her hockey team.

When it is time for Riley and her parents to move to San Francisco, Riley becomes sad and misses her life in Minnesota. When school starts, Riley starts to go from joyous and happy to sentimental and a bit depressed on account of she misses the good old days in Minnesota, not to mention that their new house is horrible and the only type of pizza they serve at a pizza restaurant  is broccoli pizza. Riley becomes even sadder and Joy does all she can to prevent this from happening. Things go from bad to worse when Sadness accidentally humiliates Riley by making her sob in front of the class while telling her class about the good old days in Minnesota (although the other kids had empathetic looks on their faces when she was crying). This causes a new core memory to be created, which is a sad one. Joy doesn't want Riley to ever be sad, so she decides to get rid of it. But during an argument, Joy and Sadness literally get lost in Riley's mind, leaving the others to try to keep Riley's head on straight, but only end up causing Riley to become rude, reclusive and cantankerous.

From there, matters start taking turns for the worst. The next day, Riley video chats with her old friend Meg from Minnesota. Things go well until Meg tells Riley all about the wonders of her new best friend, whereupon Riley, feeling replaced, gets so angry that she hangs up on Meg. When she attends the hockey tryouts, she doesn't perform too well, and she decides to call it quits.

Riley figures that since everything in San Francisco is horrible combined with her being so nostalgic about Minnesota, she decides to run away and return to Minnesota. She steals her mother's credit card and skips school to catch a bus back to Minnesota. When Joy and Sadness finally make it back to Headquarters, Riley finally realizes what she is doing is wrong and decides to run back home. When Riley returns to her worried parents, she confesses that she was pretending to still be happy and that she misses the good old days in Minnesota. Her parents confess that they miss Minnesota as well and Riley finally lets her feelings out. Soon enough, things are finally looking up for the Andersens. Riley is part of a brand new hockey team and there are new islands in her mind.

Riley's First Date?
Riley returns in the short film, where she goes out skating with a boy named Jordan (whom she met at the end of the film). Meanwhile, her parents suspect that she is going out on a date with him and the Andersen's emotions all try to find a way to make it through this, with weird and comical results.

Disney Parks
Riley's mind was built at Hong Kong Disneyland during the Coolest Summer Ever event in 2015. Guests can enter her mind and meet Joy and Sadness at the Art of Animation exhibition in the Opera House on Main Street USA.
