Something I can answer! Mick and Ick are original, recurring characters in FA. They are not a parody pair, part of a crossover, or referring to any other comic strip characters.
There was some concern in the beginning that Mick and Ick were porno characters, which they most certainly are not. I can't recall just now, but I believe that Mick and Ick are mold spores.
Hope this helps, Mitch4.
