Sin, to those who are friends with him, is a mouse of two sides. When on stage, this stripper is extremely outgoing, flirtatious, and open. Backstage, he's quiet, shy, and nervous.
Friendly and kind, the mouse is soft-spoken and courteous. While on good terms with all his fellow performers, Hyacinth is especially close to fellow mouse, Agatha. Almost to a clingy degree. She doesn't seem to mind though.
