One day, while driving through the country with his friends, Gumby finds himself to be the victim of a horrible abduction by aliens, who need his strong genes to rebuild their race. Unfortunately, Gumby isn't in a very charitable mood, and demands that the aliens give him the ultimate fuel source in exchange for his tissue sample. Since he's in no position to be making demands, the aliens agree and arrange to drop off an ultimate fuel source kit at Kapp's lab. Gumby and friends drive to the rendezvous point, stopping to tell two gas station attendants (the Blockheads) about how they're going to have the ultimate fuel source and that gas will soon be obsolete. So it's really their own fault that the Blockheads follow them to the lab and try to swipe the device when Kapp is distracted. Fortunately, the aliens have the technology to avoid pointless chase scenes by mentally taking the device out of their arms and flying it back to the lab. Kapp hooks it up to Granny's car and steals it.
