Welcome to the fantasy world of "Little Nemo," filled with dreams of enchanted lands and new friends, amazing magic and fun-filled adventure. A place where anything is possible and the only boundaries are those of the imagination. Nemo journeys to the Kingdom of Slumberland, where the king welcomes Nemo with open arms, making him heir to the throne and giving him a magical key that opens any door in the kingdom. "But I must warn you," the King says, "there is one door you must never open." Not heeding the King's advice, Nemo unlocks the door. With the King kidnapped and the nightmare unleashed upon the kind people of Slumberland, Nemo and his friends must venture into the depths of the Nightmare World in a courageous attempt to make things right.
