Moon Rockin'

'''The remaining contestants arrive on the moon and are instructed to gather both regular and silver moon rocks in one hour for the next challenge. While two contestants begin to get to know each other, another begins to suspect someone while one contestant starts earning her team's ire. During the challenge, one team struggles when a contestant goes off on her own, while another seems to prosper thanks one member's good luck. However, said member ignores her team's warnings and loses all of the group's rocks as a result. In the end, one contestant pulls off a surprise victory for her team, and a fortunate brainiac is sent home.'''
