Tree frog dragons are a subspecies of jungle sprites found in South America. About the size of a man's arm, these tiny but colorful sprites eat insects and drink nectar. Though unable to fly, they can leap great distances and stick to any surface. A fascinating characteristic of tree frog dragons is their prowess at hypnosis. They use their eyes to confuse predators and mesmerize prey. Their powers won't work on more intelligent species, but they can certainly give them a headache.
