Dr. Ernest Otter, surgeon at Hedgehog Hospital, all the way from Lake Hoohaw, dressed in a blue-green Foxerly-Clark surgical gown, white Foxerly-Clark surgical gloves, a light blue-green Foxerly-Clark tail cover, a light blue-green Foxerly-Clark surgical cap which covered his ears, and is breathing in his white MoboTech MTN95CS-M/L-W cup-style disposable particulate surgical respirator mask over his nose and mouth, to protect his lungs from any harmful airbourne particles and nasty germs. Ernest's mask also keeps his muzzle warm.
