I liked the fact that this episode starred Yang all the way through and it had a pretty interesting story attached to it. One thing I know for sure those four mysterious heads are not Wu Fu elders. Near the end of the episode you could see their eyes narrow and smiling evily. The biggest question I'm asking myself right now is what do the four floating heads want with Yang. It obviously has something to with the artifacts they want him to find, but why appear in front of Yang? Hopefully this question will be answered in a future episode.
It was kind of shocking to see a change of heart in all of the villians, excluding Ultimoose, stand up for Yang at the end of the episode all because Yang was nice and ultimoose was a jerk. Help can come from some pretty unexpected places.
Anyway I hope to see more great episodes in the future. Caio.
