Plot Outline:
Kif goes to Amy's home on Mars to meet her parents. They immediately dislike him saying he's too much of a wimp. Native Martians rustle away the family buggalo because they feel they got cheated when they traded away their land in exchange for a bead. Trying to prove himself, Kif volunteers to get them back. He does, but loses Amy in the process. The Wong's then hire Zapp Branigan to bring her back. The bead the Martians received is actually a gigantic diamond. When told of it's worth, the Martians leave Mars to buy a better planet.
