Here I analize one the trailers and try to guess what episode each scene is from. This may contain a little bit of spoilers.
Heres the Video if you want to watch the trailer:
0:01-0:02 is obvious the first episode because they are seen falling while the plane is overhead.
Im not sure of but I think it may be the 12th episode since it is called Pahk'd with talent.
0:06-0:008 is probably Mo Monkey Mo Problems because the episode most likely has to do with monkies.
ANd the rest I can't tell and am not sure off.
