Dr. Sally Acorn, former princess of Mobotropolis, chief surgeon of Station Square Hospital, dressed in a blue-green surgical gown, white surgical gloves, a light blue-green surgical tail cover which covered her tail and a light blue-green surgical cap which covered her ears and her entire hair, and is breathing in her white ROTEX 2212GN95-M/L cup-style disposable particulate surgical respirator mask (with light blue straps) over her nose and mouth, to protect her from any harmful airbourne particles and nasty germs, Sally's mask also keeps her muzzle warm.

She preferred N95 surgical respirator masks over standard, traditional surgical masks, because they were comfortable and easy to breathe, her entire staff and everyone to visit her OR should be allowed to wear them during surgery.

"Dr. Sally Acorn, the surgical masked face that launched a thousand furries." ROTEX only makes disposable respirator masks that doesn't have a metal nose strip. During the Eggman flu, Sally wore the other brand disposable respirator mask with a metal nose strip, but the nose strip hurts her nose bridge. So, she donned on the ROTEX mask because it doesn't hurt her nose bridge while performing surgery.
