Nostromoo, like his mom, is a citizen of Unikingdom. Green Mom has a square green head with a darker green rectangular holder on top of her. She has a dark green flower on the top of her head, mint green irises, and a cylindrical body with no legs. Nostromoo is a smaller version of Green Mom, but he has a solid-green triangular body and a blue flower on his head. You could see them having breakfast together in the Pet Pet episode of the Unikitty series and our fanart Unikitty Nostromoo and Green Mom cursor.
