Sir Fuzzy-Logik (aka Sir F-Fuzzy Logik) is the tenth opponent in the puzzle game Dr. Robotnik's Mean Bean Machine. He is a noble knight who carries around a trident. He, like Spike, is a threatening enemy and can cause serious issues to the player. Sir Fuzzy-Logik seems to have his own style of gameplay unique only to him. He can pull off even bigger chains than Spike. The same strategy used against Spike should also be used against Fuzzy-Logik.
Sir Fuzzy-Logik also appears in The Adventures of Sonic the Hedgehog. He chases after Sonic with other robots in one episode. He has grey fuzz rather than orange and stars on his hands.
