Mutton Chop is one of Armor Abs Krabs' Navy Buddies. He attends the "Navy Festival," where he applauds Mr. Krabs for admitting to his molten skin and hiding it from his friends. He would then proceed to remove the sideburns, or muttonchops (hence his nickname), from his face, revealing them as being false. He also appears in the game Creature from the Krusty Krab as an enemy in Diesel Dreaming.
Mutton Chop is a yellow-tan fish with bushy black eyebrows and sideburns, which are later revealed as fake. Mutton Chop also has large light orange lips. He wears a navy blue jacket over a light blue sweater. He sports a blue hat, which bears a resemblance to a conductor's hat, to complete his outfit.
Mutton Chop first appears in the season four episode, "Shell of a Man." Mr. Krabs revealed early in the episode that he was once a part of the Navy, and mentioned Chop as one of his "Navy Buddies". Chop was later seen in the episode at the "Navy Festival," where he was alluded that SpongeBob was actually Mr. Krabs. Later in the episode, after the plan had failed, Mr. Krabs reveals that he used SpongeBob as a decoy to prevent him from showing his molted body in public. Proud of Krabs' heroic revelation, Mutton Chop, along with the other Navy Buddies, reveal their unmanly secrets. In Chop's case, he revealed his sideburns were fake.
