Yosh needed something to spice up his CWDTP panel. That's when an adorable little dragon volunteered to play Spike, who has a blind Disability, at the demonstration.
Yosh is holding a fundraiser for his panel. You can learn more about it and donate at this link http://www.furaffinity.net/journal/6746129/. I think he would prefer it if you donated through paypal to his Email address.
