‘The Mandalorian’: Why Are Grogu's Eyes Black?

If you know Grogu, you have already fallen in love with him. The star child of The Mandalorian took our hearts by storm and became one of the most wholesome parts of the Star Wars universe. We had seen beings like him before, but none quite like him. Yoda (Frank Oz) and Yaddle (Bryce Dallas Howard) surely are peculiar in their own way, surprising everyone with their lightsaber skills and wisdom, what with being Jedi Masters of old. Their differences with Grogu go way beyond the fact that they could fight, though, the clearest one being the child's beady black eyes.
