Which Came First?

While going to a science museum, Billy and Mandy's schoolbus breaks down in the middle of the desert. Then, after digging for fossils, Billy, Mandy and Grim wander around and find an abandoned mine, where Billy is captured by a giant, mutant chicken. When Mandy and Grim go to rescue him, they find an underground laboratory from the days of the Cold War, where many mutant chickens were created. In the end, the mountain makes eruption, the chickens are roasted by lava, and the whole class obtains food so they don't have to resort to cannibalism. This episode might be a parody of Godzilla (1998) and Raptor Island.

Die Klasse befindet sich auf der Fahrt ins Naturkundemuseum, als mitten in der Wüste ein Reifen ihres Busses platzt. Damit die Kinder doch noch etwas lernen, sollen sie die Gegend erkunden. Billy, Mandy und Sense stoßen dabei auf eine verlassene Mine. Doch so ganz verlassen scheint sie nicht zu sein, denn Billy ist plötzlich verschwunden.

Billy e Mandy vanno in gita scolastica, accompagnati da Tenebra. Durante il tragitto, il pullman ha un guasto e i bambini rimangono in una landa desolata. Billy, Mandy e Tenebra decidono di fare un giro, trovando una caverna in cui Billy viene rapito da una gallina gigante e mostruosa.
