Mr. and mrs. Kroker are both the parents of Kif Kroker. Amphibiosans go though stages of their life, and mr. and mrs. Kroker are both colonies of flying hookworms, because they are in the last stage of the Amphibiosan circle of life. Amy's mother, Inez Wong once sprayed a part of Mr. Kroker's body until she was told by Kif about his people's evolution after apologizing she states that whatever she sprayed would grow back with all the bugs in the area. Mr. Kroker. stated "That was my left testicle !" leading to a state of awkwardness for both families much to the amusement of an observing and laughing Bender.
