Captain Sassafras is an elderly Walrus who drives a submarine underwater.
Captain Sassafras is a kind Walrus who loves to hear music, as he mentioned in "Pig Goat Banana Cricket High Five!" However, when Goat played her song for him, he asked her to get out of his submarine. This likely means that he is tolerant of annoying things to a certain level.
Captain Sassafras is gray in color and has a blonde mustache and blonde hair. He wears a navy tuxedo and a white sailor's hat. He also has a pink nose and large white tusks.
