As a twisted figment of Riley's encounter with clowns, Jangles is a giant clown with blue hair, a white face with a creepy smile, a large red nose, and bright green eyes. He is dressed in a red top and blue polka-dot pants with big floppy shoes and carries a huge mallet.
In real life, Jangles was an entertainer who attended 6 years of drama school prior to his job. When he was hired for Riley's third birthday party, Riley became so scared of him that it traumatized her. The experience created a psychotic, exaggerated version of him within Riley's mind and was kept in Subconscious. When Bing Bong is put into Subconscious, he is imprisoned on top of the slumbering Jangles. After Joy and Sadness rescue him from Jangles, Joy wakes him up to get Riley awake so they can use the Train of Thought to get back to Headquarters. Luring Jangles into Dream Productions, Riley captures his image in her dreams and wakes up. Joy, Sadness and Bing Bong then hop on the train and escape the rampaging Jangles.
During the credits scene, the real Jangles is seen at a birthday party. A look into his mind reveals he secretly hates his job.
- Several Pixar employees confirmed that Jangles is a tribute to their old friend, Joe Ranft, who occasionally dressed up as a clown.
- His appearance, as well as his name, is similar to Chuckles the Clown in Toy Story 3.
- He is the closest thing to an antagonist in the film.
