When Master Yo was in Clown Fu training, he had a magical wig called the Tooty Fruity Fro of Double Duty that had the colors of the rainbow. The four Woo Foo Elders sent Yang to recieve it, because Yang needed it to make the armor that could stop "The Dark Tommorow." When Yin and Yang got there, they learn the magic of Clown Fu and got the Tooty Fruity Fro of Double Duty and a unicyle, respectively. The clowns took it from Yo, because he didn't save them from the Numbercrunchers therefore he was kicked out and went back to Woo Foo, just like Yang. When Yang got the Tooty Fruity Fro of Double Duty, he was considered a Clown Fu master.
