The main character and protagonist of the story. He suffers from constant nightmares. Nemo is around the age of eight and is a generally sweet boy who loves the circus. However, he has been known to lose his head now and then, such as when the princess makes fun of his pajamas and refers to Icarus as a "little rat." He has been summoned to Slumberland by Professor to be the Princess's playmate and (as he finds out later) the future prince of Slumberland.
