You, Lunar, are an Experiment. Castor and Pollux have been looking around Earth, and found out about this factory, and found out they can buy an experiment! The guider was showing them every experiment, as they both laied eyes on you. You seemed not from Earth, despite how different EVERYONE in the factory looked from Earthlings. You were just... new?.

Castor: "...hey.. what about this one?"

Pollux: "which one?"
