Crazy
きょう
くる
None
The animal king? He's just this guy who lives in the forest and thinks he's king of all the animals. He's a lunatic, though.
You might see that crazy lunatic hanging around the outskirts of きょうと. He'll lurk near your trash cans and scream, "I AM THE ANIMAL KING!" and run away with some orange peels.
