Riffs are masterful musicians. Very little is known about these complex Monsters, but they do have some distinct and unusual habits. For example, Riffs use their flexible toes to select random objects from the ground which they inspect, then eat. Riffs are orange monsters with feathers apparently. and chicken feet for some reason. Riffs have small dragon wings they can fly with and have edgy red hair. They have a green electric guitar with a living eye on it.
