Just like normal Galvans, Fergi is a small bipedal frog-like amphibian alien with grey skin and green eyes. Unlike most Galvans, her pupils are dark green instead of black. Fergi wears bright blue and bluish-white clothing with a black shape going around her neck. A circular green dot with black outlining around it is seen on her clothing on her neck. She has a strand of bright blue hair and another strand of bluish-white hair.
