— Rockhopper's Joy
Rockhopper's Joy is the penguin manifestation of the emotion of joy within Rockhopper. Players could obtain her costume at the Inside Out Party. She is the main emotion at the party and in the film.
During the party, Rockhopper's five core memories go missing, with one corresponding to each emotion. Rockhopper's core memory for Joy was finding Yarr, his Red Puffle.
