Goose is charged with keeping Daisy O'Mega, the leader of the group of outlaws, distracted after she makes it plain she is attracted to him.

Old Roy McIntyre's at it again! The prospector and Burr-O 5000 are on C-40, yet another planet in his never-ending search for the mother lode. Using his high-tech divining rod and his space-pick, he strikes it rich, uncovering a huge deposit of Starstones. But it isn't long before word spans the galaxy and the "gold rush" is on.
