Slurms McKenzie

Slurms McKenzie is a giant, sunglasses-wearing party slug who slides into the Planet Express crew's lives as a mascot of pure hedonism. He exists to throw down, chug whatever's offered, and dispense catchphrases about partying. His whole personality is enthusiasm for good times, with zero interest in consequences.

He's a one-joke character executed with total commitment — a slime trail of frat-boy bravado stuffed into a mollusk body. David Herman plays him with a stoned, blissed-out drawl that makes every 'party' pronouncement funnier than it should be, and the show trusts the absurdity of a slug being the coolest guy in the room.
