His singing can make your ears bleed, unless you cover them, stop hearing it, and or are deaf. He can smell blood from over a mile away. He kills people by singing and then eats their corpses. He will giggle and will act lightly if you don't die. All animals that understand the language he's singing in and if they can hear it, will die. He speaks and understands German, Arabic, and English. He doesn't understand new internet lingo.
