at their wedding at the Crack of Doom, hours before the arseteroid is due to hit the site. Robobum is carried away by a bumodactyl up to its nest, where Eleanor discovers her bum being fed to its chicks. Eleanor and Zack rescue Eleanor's bum before the Great White Bum arrives, but returns to see that the Kisser has shot Ned dead. Realizing that the Kisser is still allied with the bums, Eleanor and Zack subdue him by sucking his liquefied body into a vacuum cleaner. Eleanor's bum, who had jumped in front of Eleanor to stop her from being shot, is saved by Zack's bum. Ned's corpse is teleported out of Robobum, so that he can rest in peace.

Zack's bum, however, admitted that he used Robobum's interplanetary death ray to kill any life on Uranus in the time that Zack and Eleanor had gone to save Eleanor's bum from the bumodactyls. Accepting defeat, the Great White Bum cries as the arseteroid hits the wedding ceremony. For unknown reasons, Zack and Eleanor wake up in a barn owned by Ed Kelly, and return to their homes in Marbletown. The two float the possibility that the impact of the arseteroid opened a brown hole, which transported them into the future that they had created. Along the way, they realize that their fellow bum-fighters have jobs in other fields, and that Zack's grandfather and Eleanor's mother are alive. They learn that Eleanor's father
