Mounds is known for her extremely large breast implants.
Mounds' implants are polypropylene string breast implants, which irritate the breast tissue, causing them to grow continuously as they fill with fluid. Mounds holds the Guinness World Record for the "World's Largest Augmented Breasts".
The fluid is absorbed by the implant, resulting in continuous, gradual growth of the breast.
