This show is about two anthropomorphic rabbit twins named Yin and Yang that train under Master Yo, a grumpy old panda who ends up being their father. They learn the sacred art of Woo Foo, a special type of martial arts that involves might and magic. They must work together to save the world from evil villains and forces that want to destroy, corrupt, or take it over. But through all these adventures, Yin and Yang still portray typical siblings; sometimes disagreeing with each other, but still care about each other and working together when needed.
It had to happen sooner or later, but Yin and Yang have found out that they have real parents! The Woo Foo Warriors decide to search for them, but this search is leading them to an encounter with an old, dangerous enemy! And which evil enemy is behind the fiery attack of the city the Woo Foo Warriors live in this time? More information will be added in later when the episode actually airs!
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, meaning Yang and Yin are going to have to guide the two Woo Foo Warriors in a little less training 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 at the spa he's vacationing at, when who should Master Yo run into except Eradicus! Unable to fight each other on spa grounds, can Master Yo and Eradicus possibly keep their tempers in check while they're both vacationing with each other?
Carl captures Lena and throws her into our dimension on Earth, into the home of Jason Earles! While Jason Earles is having an awesome hair rivalry with Mitchel Musso, Yin and Yang are forced to find her in what they think (and by their standards, rightfully so) a very strange, new world. Meanwhile, Carl also gets pulled into our world by Yin and Yang, and finds out that he might just be able to inflict more fear and chaos in our dimension then he can in his own, and manages to create his own cockroach army!
Party Troopers: Yin and Yang decide to throw a party even though Master Yo tells them not to. So Yin and Yang throw a party, inviting anybody and everybody cool to the Dojo. But what they don't realize is that Eradicus plans to send his minions to the party, determined to destroy Yin and Yang before they can get their army organized! Will Yin and Yang's friends come through in a pinch? Shadowcluck: Yin and Yang have their army, but their army is less than organized and/or effective. Thankfully, Coop has come to lend his hand to their efforts.
Clothes Encounters: Yin and Yang don't want to do laundry. But they're about to find out when they ignore something long enough, it grows into a problem too big to ignore. Now their laundry pile is a monster running through town, and they need to stop it before anyone finds out Yin and Yang made this problem or worse; Smoke and Mirrors capture the monster for their own nefarious ends!
