Orcs are not funny Mickey was the 3rd victim of the Orcland Greens (actually 4th, but thanks to the Doc Moses Ripley is still intact).

Mickey actually liked the game, but getting injured meant he would less likely get away from his opponent in time, hence more likely eating dirt! And Mickey does not like the taste of dirt - especially when its mixed with his own blood!

After a short carrier Mickey decided to earn his fame somewhere else. His not sure where though, but he knows life of a rat is full of opportunities, so he will just wait till one comes along!
