Clay Fighter

ClayFighter is a fighting game released for the Super NES in 1993, and later ported to Mega Drive/Genesis in 1994.

Most of the game features a circus theme focused more on humor than serious gameplay. It features high-quality, claymation-style graphics that were created by photographing and digitizing actual clay models.

A meteor made entirely out of clay crash-lands on the grounds of a humble American circus. The goo from the interstellar object contaminates all of the circus' employees, transforming them into bizarre caricatures of their former selves, with new superpowers.
Characters

The game features eight wacky characters and one boss character:

Bad Mr. Frosty - A snowman with a bad attitude. His special attacks include throwing snowballs, spitting sharp balls of ice, sliding along the ground and kicking his opponent, and turning into a snow boulder and rolling into his opponent. His arena in 1-player mode is an icy lake with penguin spectators.

Blob - A blob of clay. A self-proclaimed master of "goojitsu", his specialty is "morphing" into objects to attack his opponent, with his specialty being transforming into a buzzsaw and cutting his opponent in half. He is said to be highly intelligent, despite being made up of the slimy dregs of the mutagenic meteor. His arena is a pool of green slime.

Blue Suede Goo - An Elvis impersonator with wildly exaggerated features, including a big gut and even bigger hair. He throws musical notes at his opponent and used his hair as a blade. He fights on the keys of a flaming piano with the words "Big Hunk O' Burnin' Clay" (A parody of the Elvis song "Hunka Hunka Burnin' Love") on it.

Bonker - A cheerfully manic clown whose arsenal includes deadly pies, killer cartwheels, and the big hammer that gives him his name. He will fight in two funhouses, one resembling a clown head, the other resembling a bubble-spewing rubber duck (Although their interiors are the same, save for a palette swap).

Helga - An obese opera singer and Blue Suede Goo's rival. She attacks by hurling herself at her opponents, stabbing them with the horns on her helmet, and by hitting that high note for a sonic scream. The first foe in 1-Player mode, she will fight you on stage at an open-air opera theatre.

Ickybod Clay - A ghost with a pumpkin head. He can teleport, and throw balls of ectoplasm at foes. His name is a play on Ichabod Crane from Sleepy Hollow, and his pumpkin-head is likely based on the Headless Horseman from the same tale. His arena is a haunted house, unsurprisingly.

Taffy - A fighting piece of Taffy whose attacks mainly involve stretching far and twisting his super-flexible body. In 1-player mode, he will fight in two overflowing taffy factories.

Tiny - A wrestler type character who doesn't really rely on wrestling. Instead, he uses his big fists to charge across the screen and punch, as well as rolling himself into a ball and flinging himself at foes. Another foe with two palette-swapped arenas, he will fight in a wrestling ring or at a colluseum.

N. Boss- The final boss is an odd necklace-like creature. Looking like nothing so much as a string of pearls with two round eyes (one wide-open, one half-closed), N. Boss only attacks with projectiles copied from other characters and a grab attack. Unlike the other characters, he doesn't actually appear to be made of clay and the announcer doesn't announce his name at the start of the match or when he wins, both suggesting that he was thrown in at the last second just to have a final opponent to face. His name is a pun, poking fun at both M. Bison from Street Fighter II and the phrase "end boss".
