Harold and the Purple Crayon

Harold, a young boy, discovers a magic purple crayon that brings to life anything he draws. He begins creating friends like Moose and Porcupine, expanding his own imaginative world. As he grows into an adult, his imaginative adventures continue with his friends.

Harold and his friends hear the voice of Crockett Johnson, the creator of their world, who admits to creating them. Johnson disappears suddenly, leaving Harold unsettled, prompting him to seek out his creator himself. Harold draws a portal to the real world to find Johnson.

Harold, Moose, and Porcupine travel through the drawn portal, entering the real world. Moose transforms into a human but still becomes a moose when scared, and Harold explores their new environment. They encounter Terri and her son Mel, where Harold draws and rides a bike.

Porcupine follows through the portal but gets separated when the door closes behind her. She later finds and breaks into a house, eats cake, and causes an alarm, drawing the attention of police. Meanwhile, Harold and Moose continue their quest to find Johnson.

Harold befriends Mel, a boy who feels out of place at school. Mel shares his imaginary friend, Carl, with Harold. Together, they work to find the 'old man' who created Harold, and Harold demonstrates his magic by drawing and creating a spider-fly for Mel.

Harold, Moose, and Mel visit the library and encounter Gary Nastwick, a failed fantasy writer. Gary attempts to sell his books and shows interest in Harold's world, noticing Harold using his magic crayon to draw a plane, which reveals Harold's origins to him.

Harold and Moose fly through the skies using the magic crayon, but Moose’s transformations cause them to abandon the plane and parachute back to town. Mel faces bullies at school but defends himself using his draw of Carl to summon a creature.

Harold and Moose get involved in Terri's retail job, drawing animals and flying objects that cause trouble and get her fired. Terri joins the group as they walk through town, where Harold creates a piano for her to play, helping her reconnect with her love of music.

Gary finds Harold and his friends and attempts to seize the crayon, revealing his plan to create his own world. Porcupine is chased and captured, and Harold, Moose, and Porcupine are arrested after a confrontation with the police.

Mel uses a piece of broken crayon to draw a key, freeing Harold and others from Gary’s trap. During the showdown, Carl breathes fire to distract Gary, while Moose and Porcupine come back to life to help defeat him.

Harold draws a door that allows Gary to enter a fantasy world of his own creation, including a clone of Terri. Grateful but disappointed, Gary enters the world but is ultimately prevented from returning when Carl burns down the portal.

Harold and his friends visit a museum dedicated to Crockett Johnson’s works, where Harold finds a note from Johnson encouraging him to keep believing in himself. This inspires Harold to continue using his imagination and sharing it with others.

Harold, Moose, and Porcupine return to their world, bringing crayons of different colors to keep building and imagining new worlds. Harold feels more confident about his creative powers and their importance.

During the credits, Gary tries to make a move on Zerri, the Terri clone, only to discover she is already in a relationship with a wizard from the fantasy world. This comedic ending hints at his continued obsession with creating his ideal world.
