Rotor Walrus, dressed in a blue-green surgical gown, white surgical gloves and a light blue-green surgical cap, and is breathing in his white 8M 1870+ flatfold-style disposable particulate surgical respirator mask (with red straps) over his nose and mouth, to protect him from any harmful airbourne particles and nasty germs.

The 8M 1870+ masks has a best fit on walruses like Rotor, Lady Walrus and Willy, chameleons like Espio, polar bears like Bark, weasels like Nack and Nic and avian Mobians like Jet, Wave and Storm.
