Farfel Bainbridge
Farfel Bainbridge is an art evaluator who first appeared in the episode, Fiasco!. He is capable of sniffing out artwork and determining its value through its scent.
Farfel introduced himself at the Krusty Krab, during an argument between Squidward and Mr. Krabs over whom Fiasco's artwork belongs to. Using his ability to sniff out artwork and determine its value, he declared the piece a national treasure, thus meaning neither Squidward nor Mr. Krabs own it; it belongs to the people of Bikini Bottom. He places a glass cover to protect it from the air and laments that it has to be shown in a "greasy spoon". Mr. Krabs takes umbrage at this and asks, "Oh, so you're a food critic, too?"
He is purple with a dark purple fin, a pointed snout, and sharp teeth. He might be a shark because of his teeth, or a billfish (like a marlin), since his fin is closer to that of a billfish than that of a shark.
Mr. Krabs called him "Farkle".
