The Sandcastle Girl is a hotel guest that is seen building sandcastles on the beach, hence the name. In "Surf Surf Revolution", she was seen in line to play STOKE. In "Browatch", she was building a sandcastle before Broseph helps her. In "Dirty Little Secret, Nerdy Little Secrets", she is seen cringing in disgust when Mrs. Nichols threw up in her sandcastle.
