Eradicus decides that the best way to fight the Woo Foo Army is to divide them and then conquer them. He sends his minions Ella Mental and Indestructo-Bob to destroy Dave and Jobeaux respectively. That means Yin and Yang will have to guide the two novice Woo Foo Warriors to exceptional heights and inspire them to become stronger fighters if they want to have a shot at beating evil. Meanwhile, Master Yo has problems of his own during his vacation when he runs into Eradicus. Unable to fight each other on spa grounds, Master Yo and Eradicus have to keep their tempers in check while they're both vacationing with each other.
