The Brute Fish is a very muscular and rather disturbing purple fish seen (currently) twice throughout the series. Once in "Sentimental Sponge" as the garbage man, as well as "Kracked Krabs" as a hotel bellhop.
He has purple skin and a very muscular body. He seems to always be frowning or be angry. His clothing depends on his occupation. In "Kracked Krabs" he wore a green bellhop uniform and in "Sentimental Sponge" he wore a white shirt and overalls. A large, pink vein is visible on the right side of his neck.
