Casper, Wendy, and some of the other forest folk rescue a boy named Oliver Ergo from Bruto the ogre. When they ask him where he comes from, he points to the moon, so they rig up a spaceship powered by witches' brooms.; Casper and Wendy discover that what we see as the moon is actually a round opening into a land with yellow sky, "Oppearth Land," where everything is backwards from Earth (much like Bizarro World). Oliver, known as Revilo here, takes Casper and Wendy to Ye Olde Wrecking Shoppe, where they pick up a package.; Casper, Wendy, and Oliver return to the forest and it is revealed that Oliver is actually Bruto's son, and that he had called for help because he had nobody to play with. Bruto wouldn't let him play with the forest folk because he was mad at them for stealing his guadrulnik years ago--but the guadrulnik is in the package Oliver has brought from Oppearth, where Bruto had taken it for repairs and forgotten about it.; Two ghost kids come to Spooky for booing lessons, but he's afraid of making Poil mad.; Spooky catches a burglar in his house.; A boy with elevator shoes gives Spooky an idea.; Casper prefers representational art to abstract art.
