The king of Slumberland and the Princess&#039;s father. He ordered the Professor to bring Nemo to Slumberland to be his daughter&#039;s playmate. He shares an interest of trains and machinery with Nemo, who grows very dear to him. The king, in spite of his expected responsibilities, has a habit of sneaking off to his playroom (where he accidentally runs into Nemo who, at the time, wasn&#039;t aware of who he was). Morpheus decrees that Nemo is to be trained to be Prince of Slumberland and gives him &quot;The Golden Key&quot; which can gain him access to anywhere in Slumberland (provided Nemo promises not to open the door with the same symbol as the key on it). He gets kidnapped by the Nightmare King at Nemo&#039;s coronation, prompting Nemo to set off after him, along with the Princess, Prof. Genius, Icarus, and Flip.

Welcome to the fantasy world of "Little Nemo," where dreams of enchanted lands and new friends take young Nemo into an exciting, fun-filled adventure through Slumberland. On one unforgettable night, Nemo falls asleep. Soon, with the help of his flying pet squirrel Icarus and his friend Professor Genius, they journey together into Slumberland. Nemo is lovingly embraced by the people of Slumberland, particularly the King, who adopts Nemo and makes him heir to the throne. He is entrusted with two very special possessions: the prized royal Scepter, and a mysterious key that unlocks many secrets!<br>
<br>
Though Nemo is warned not to open the one door with the power to destroy Slumberland, temptation proves too strong and the King is abducted as a black cloud of nightmares washes over the formerly idyllic dreamscape. Now, if Nemo is to reverse his error and bring the King back, he must rally his friends and journey deep into Nightmare Land.<br>
