Joy is the main protagonist, heroine, and narrator of the 2015 Pixar film, Inside Out. She is the yellow emotion and one of the five emotions inside the mind of Riley Andersen. As her name implies, she is eternally optimistic and appears to be happy all the time and thus could be the leader or enthusiast of the group, hence her name. She can sometimes be miserable about the important memories in Riley's mind, though. She is voiced by Amy Poehler who also did the voice of Bessie Higgenbottom from The Mighty B.
