Adelaide is a small, light-skinned girl, with brunette hair tied into pigtails with red bands. She wears a sleeveless red blouse with a white collar, along with a purple skirt, and black sneakers. Before The Casagrandes started airing, like Sid, she did not have eyelashes until the show was aired.
Trivia
Adelaide was one of the few female characters who did not have eyelashes, along with Sid, before the animators gave both of them eyelashes in The Casagrandes.
She has similarities to Lana. They both have an extreme love for animals (especially frogs), they both wear their hair in pigtails, and they are both six years old.
