This chicken happened to cross Shadow Zibonzi's path. In less than three seconds, he was almost completely covered in sculk, one of his eye put out by the glowing substance and his wings unable to fly or slow his fall anymore. His beak also is obstrued by sculk. Since some of his most important body parts are paralyzed by the sculk, he will soon die if nobody gets the sculk off him. And when that chicken dies, he'll spread a puddle of sculk that will slowly infect nature nearby...
