Sissy is a child who was a visitor at the Monster Carnival on Monster Carnival with her brother, Bubby.
Entrusted to her brother's care, Sissy visits the carnival with the sole purpose of bringing a teddy bear home. She is first seen in front of the Mirror Maze where she tells you that Bubby is going to win her a teddy bear later at the carnival. While at the Pop the Balloon game later in the day, you find out that the darts used in the game have been blunted and the balloons are not popping. As a result, Bubby was unable to win Sissy a teddy bear, making Sissy vow to tell their mother about it. She was also caged up by Ringmaster Raven, along with the other carnival visitors, to be hypnotized and turned into his slave.
