Nemo (Japanese: ニモ) is a side-scrolling fantasy arcade game released by Capcom in 1990. The game is based on the anime film Little Nemo: Adventures in Slumberland.
Nemo travels with a circus parade to Slumberland to meet King Morpheus. He is accompanied by Flip to fight through the now-dangerous enemy-infested Slumberland to find the king. At the heart of the kingdom, Flip tempts Nemo to open the sealed door, unleashing the Nightmare King, who kidnaps Morpheus along with his daughter Princess Camille.
Nemo and Flip battle through the lands of Nightmares to rescue the kidnapped monarchs. They infiltrate the Nightmare King's castle, before fighting the evil king himself. After the Nightmare King is destroyed, peace is restored to Slumberland.
