This is Samson, the Project FIMiley version of Spike.
He's a cute bubbly dweeb and is based on an African fat tailed gecko. Being raised by horse girls, he never learned how to be a big tough dragon, so the name Samson seemed to fit, seeing as how the biblical Samson was weakened by a woman. He's an earth dragon, and they live underground, breath fire, and don't fly.
