Mumble looks like a baby penguin. His grey feathers when baby appear and closing half of his body. But still has light blue eyes, Black and white feathers, and normal emperor penguin beak and feet. But he has a bow in front of his neck and has three black spots on his leg feathers that give the appearance of spats. His grey feathers resemble a vest. That is what Mumble looks like!
Hope this helped!
