A small, fluffy unicorn is born in the Delicious Heart Forest. Although everyone thinks he's incredibly sweet and feeds him sugared lucky grass, he doesn't behave like a unicorn at all. He constantly says NO to everything, so his family calls him the NOhorn. One day the NEEhorn escapes from the Heartwood and meets a raccoon who doesn't want to listen, a dog who really doesn't like anything and a princess who doesn't agree with anything. They go out together. Because being grumpy together is much more fun!
