Lunatic, Crazy
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.
While we're speaking of animals, he's absolutely bat sh*t crazy.

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.
I think he maybe got too friendly with some raccoons and beavers and went crazy. Watch out for him if you live in きょうと, rabies is no joke.
