Nurse Sunset Shimmer, scrub nurse at Ponyville General Hospital, dressed in a dark blue EquestriTech surgical gown, light-blue EquestriTech surgical gloves, a light-blue EquestriTech surgical tail cover which covered her tail, a light blue EquestriTech surgical cap which covered her ears and the most of her hair except for the back and her horn, and is breathing in her white EquestriTech EMCSN95-M/L-W cup-style disposable particulate surgical respirator mask over her nose and mouth, to protect her lungs from any harmful airbourne particles and nasty germs. Sunset's mask also keeps her muzzle warm.
