Spud! is quite large, towering over human characters as seen in comparison images. His big, hulking frame gives him a gentle giant appearance, perfect for cuddling and protecting others. His body is covered in thick, fluffy white fur. The fur is soft and seems to extend from his head all the way down to his large paws and no legs, using his arms to function as legs. The fluffiness adds a sense of warmth and cuddliness to his character. Spud! wears a bucket hat adorned with stickers, etc.
