He has black eyes, a small gap on the right side of his upper jaw, three fingers on each hand and two toes on each foot.
Mikey wears an orange mask over his eyes (with short mask tails), orange wristbands and color-matching socks and orange knee pads with faces drawn on them (dead face on the right and smiley face on the left). He also wears a light brown belt around his chest and strap over his right shoulder, as well as a Turtle emblem over his heart.
