Karuso, the coral keeper

Playing catch outside with his friends, Karuso accidentally hit his head on a wall and lost his consciousness. He sank into the foggy depths of the swamp. After laying on the ground of the swamp unconscious for seven days, he woke up and realized his body, especially his left arm, was overgrown with corals. At first he tried to get rid of them, but then he realized that they probably saved his life by protecting his body from the giant deep sea creatures. Now he embraces his coral friends and lives in symbiosis with them. He even uses his arm to paint with it.

I hope you like this little guy!
