Little Nemo: Adventures in Slumberland

Nemo experiences a vivid nightmare where a menacing locomotive chases him through a dark landscape. The dream leaves him shaken and convinced that the night can hide real dangers. He wakes with his heart racing, unsure if the danger has ended or merely shifted.

The following day, Nemo and his flying squirrel Icarus look forward to a parade welcoming a traveling circus. His parents are too busy to take him, so he feels left out of the spectacle. The unfulfilled wish foreshadows his later longing for belonging.

Nemo sleepwalks to steal some pie, breaking a promise to his mother. She catches him in the act and sends him back to his room empty-handed. The incident intensifies his sense of rule-breaking and yearning for a touch of magic.

Dream figures from the parade arrive in Nemo's sleep. Professor Genius introduces himself and explains a mission from King Morpheus in Slumberland. Nemo learns that he must become the playmate to Princess Camille, swayed by a gift box of cookies.

Nemo travels to Slumberland in a dirigible he is allowed to pilot, causing playful chaos. He is introduced to King Morpheus, who declares Nemo his heir and gives him a golden key. Morpheus warns him about a forbidden door bearing a dragon insignia.

Nemo meets Princess Camille and the two begin exploring Slumberland together. Their budding friendship grows as they roam the kingdom's wonders. Nemo wrestles with his initial hesitation about befriending a girl.

Flip tempts Nemo to skip his prince lessons, triggering a chase and a hideout in a cave. Nemo discovers the door Morpheus warned him not to open and faces the temptation to unlock it. The urge to see what lies beyond tests his restraint.

Unlocking the door releases The Nightmare, crashing the coronation festivities at Morpheus' castle. Nemo dashes back with the key, but The Nightmare arrives and abducts Morpheus. In the confusion, Nemo is blamed for enabling the threat.

Nemo awakens to a seawater flood in his room, ejecting him and Icarus into the ocean. Genius consoles him and urges him not to blame himself, urging a quest to rescue Morpheus. They set off with Camille, Flip, and Icarus to find the map and return to Slumberland.

The team sails in a tugboat and is sucked into a whirlpool that transports them to Nightmare Land, where goblins called Boomps join their mission. They fend off a flock of giant bats sent by the Nightmare King and push forward in hopes of saving Morpheus. Nemo reaches for the scepter but memory gaps force them to retreat and regroup.

The Boomps reunite with Oompo, who delivers a letter from Morpheus containing the full scepter incantation. The group travels to Nightmare Castle through a sky portal and confronts the Nightmare King, who threatens their captives to compel Nemo. After a fierce battle, Nemo wields the scepter to begin defeating the Nightmare King.

The battle seemingly costs Nemo his life as Nightmare Land is purified and Morpheus mourns. Morpheus uses the scepter to revive Nemo, praising his courage and declaring him a true prince. Slumberland celebrates the fall of the Nightmare Kingdom and Nemo reconciles with Camille.

Camille escorts Nemo and Icarus home on the dirigible as Slumberland rejoices. Nemo and Morpheus reassure him of his bravery and his rightful place as a prince. He shares a kiss with Camille before returning to his world.

Nemo wakes in his room and apologizes to his mother for breaking his promise and trying to take the pie. His parents agree to take him to the circus, fulfilling the earlier plan. He looks out the window with Icarus, ready for a fresh day together.
