K'nuckles' Parents are first seen in the episode K'nuckles Is A Filthy Rat, where it is revealed that they have been turned into seagulls by a magical genie, but might have not been true since K'nuckles was "intoxicated" at the time. In Diamonds in The Stuff, One of K'nuckles' parents (his father) was shown before being turned into a seagull. Which possibly means that he got turned into one while he was away,(however in the same episode it's implied that he died so it's likely that he is not a gull).
