Professor Sophia Sylvan is a former gastric performer who is now a quirky professor who teaches her students biology but also about the gastric arts. Sophia was a renowned circus performer known for her stomach capacity and her dr1nking abilities. She teaches about the digestive tract in a fun way, engaging the class before demonstrating for them how they too can push their limits by consuming two litres of soda or water at a time. She continues to tell stories from her college dr1nking days, about how she learned she can get attention for keeping up with the boys and freely burping and chugging drinks. She also tells how she was discovered in a bar for her dr1nking capacity and how she joined the circus. She does all this while burping loudly and hiccuping, with her swollen belly bursting out of her tight pencil skirt and button up top. She has a request to show off how huge and bloated her belly is after dr1nking two litres of soda and she pulls up her skirt and slaps her firm swollen belly while swearing her students to secrecy about her unconventional teaching methods.
