Little Nemo is given an endless bag of candy by Princess Camille of Slumberland. He can use this candy two ways. The first use for the candy is to throw it at some certain creatures that are encountered in all areas of the game. After the creature chews three pieces of candy, it will fall asleep. When this happens, Little Nemo can either ride or "become" the creature. Some of these animals have an ability to defend themselves. The player discovers these abilities as they play the game.
