Yellow Guy is a yellow-skinned humanoid with a round, orange nose and short, blue spiky hair. He wears blue overalls with a "D" stitched on the front. Yellow Guy embodies innocence and naivety, often displaying childlike qualities. He is curious, very easily influenced, sensitive, and has a love for nature. His lack of intelligence stems from his old batteries. With new batteries, he becomes MUCH more mature and intelligent. He lives with his friends, Red Guy and Duck and favors the color green.
