Ravio is a character from the new Legend of Zelda game, A Link Between Worlds. He is a traveling shopkeeper dressed as a bunny, who sets up shop in your house. You can buy or rent any item you need from him. Also, here's the Link (lol) to La_Pixel's contest: http://www.planetminecraft.com/forums/simple-but-detailed-t336043.html

Because his identity is a secret, and is revealed later in the game, I don't want to spoil it, so I left his face blank. I put an alternate version with his face in the spoiler below.
