Dandruff is a defective Irken.
Dandruff has more circular eyes than other Irkens. His eyes are brown. He is of average Irken height.
Dandruff is defective only because he acts a lot like a cat, meowing and chasing balls of yarn. He also coughs up random hairballs. He rarely says anything comprehensible, and likes to eat anything that's been in the water.
