Wanna know how did Bob Boyle came up with an idea to create this show??
all the answers are here...

Bob Boyle, the show's creator quoted in an online interview: "That idea came from a trip my wife and I made to Little Tokyo (in Los Angeles). I saw a little girl wearing a shirt that said 'Samurai in Training.' I thought that's cute, and then that a tiny samurai would be not only funny, but hilarious!! and then went to 'what is the cutest' animal and thought of a fluffy little bunny and it took off from there. Always hearing from folks in pitches that an idea didn't have enough boy appeal, or enough girl appeal, I thought why not do both. Have equal characters, or equal importance, boy and girl. Then give them that sibling rivalry." Yo was added a bit later on. Thus, Yin Yang Yo! was born.
