Yin Yang Yo! is an animated television series created by Bob Boyle (also the creator of Nick Jr. series Wow! Wow! Wubbzy!). It is produced in Burbank, California and Toronto, Ontario. It is the third Jetix-original show. 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 needed. The setting is in an Asian part in Chicago. The town's buildings have an Asian style. The residents are monsters, humanoids, robots and animals with human-like qualities and behaviors. The residents keep unusual pets like puppygriffs, creatures that are half puppy and half griffin, as well as real animals like dogs, cats, opossums or armadillos. Magic and martial arts still exist since ancient times when the Night Masters were around.
