The Fire Breathing Lizard is a creature owned by No Heart that only appears at the end of The Great Race . It is used by No Heart to make Beastly run on a treadmill for punishment, because Beastly failed No Hearts plans again.
It is a tiny, green, unidentifiable reptile with a crocodile-like snout and a long thin tail that breathes fire. It also has black hair and yellow eyes.
It is unknown if it is a small dragon, what is pretty much unlikely, since this already by it's looks absolutly unidentifably as one, and also, dragons are not known for breathing fire, what this creature is doing. Also it is unknown where No Heart got if from.
