The Night Master, thought to be forever defeated, comes to Yin and Yang with promises of power and glory. Will the siblings be able to resist the temptations of evil and remain true to their noble destinies?


The episode starts in a flash back. The night master is talking about the old days when he was running the town and spreading evil. Yo was a great woofoo warrior who defeated the Night Masters army. But using the amnisulet he and everyone else s mind was erased. Now everyone thinks woofoo is stupid and so is any one who practices it. The Night Master now plans on freeing his army from the spell Master Yo used. So the Night Master starts a dodgeball tournament. Yin and Yang were not told about the tournament so they want to to show people that woofoo is still good. But then Master Yo won't let them because bad things happen when they use woofoo in anger. So they sign anyway up with Coop and are easily defeated. So the Night Master offers to help them and they agree. In the first lesson he tells them to use mad emotions when they refuse he makes them angry and they learn how powerful they when they are angry. So the Night Master keeps helping them and they start winning. They make it to the finals whhere they face Ultamoose's team where they become so angry the reach a score 29 right befor they were going to win Master Yo stops them then Coop throws them the ball and they get the last point. Then the Night Masters army is released from the spell and everyone runs. Yo becomes unconscious and Yin and Yang trap the Night Master and leave with Yo. At the end Coop is revealed to be working with the Night Master.
