Sam your enemy (teach the cat)

Sam's appearance:
Sam is a white chimera rabbit with a black snake tail and green-yellow eyes. His long blue bunny ears are fake; underneath them are blue cat ears, but he never takes off his blue bunny ears. His eyes are green-yellow. When Sam gets overexcited or feels very emotional, his mouth becomes vertical, and when things get really bad, it almost splits his head open. He has sharp teeth and a very long pink tongue. When he's excited, very happy, or angry, his pupils fill almost his entire iris.
He doesn't wear clothes, he only covers himself with wool.
