 A bunch of evil Moon Fiends attacked Johnny and Dukey in outer space when they came to the moon to do research for Johnny's paper.The army of Moon Fiends ate a lot of spice cheese nachos, which gave them stink gas and fart on Johnny and Dukey.The leader sent all moon fiends, and later mega fiends, to attack the duo, only for Johnny to use the knowledge from his report (and the report itself) to defeat them all and escape.
