- “The world wouldn't know my name!”
At some point, Uma was given a sandbox along with a shrimp by Mal, who then nicknamed her "Shrimpy". She wanted to join Mal's gang at some point but was told she wasn't big or bad enough.

Uma has slender, tan skin, dark brown eyes, long aqua, black and white hair, brown eyebrows, wears her mother's necklace around her neck, usually dressed in pirate clothes, usually wears bracelets on her wrists, and turquoise nail polish. As a giant cecaelia, she has aqua colored tentacles.
