Strong potential
First of all: I like it. But, I really think there's a lot you could change to improve it. To start, the voices... they're all well acted, but I really think this story could be told better without spoken word or subtitles or anything. Word bubbles with pictures and a little emoting could convey the entire story. I like the monkey soliciting for sex, but, again, that could be shown with a word bubble with a bed moving back and forth.
So, there'd need to be a little bit of rewriting, but I think ditch the script and the voices, use your awesome animation talents, convey the story non-verbally, and remember that simple and clear ideas are best for humorous SMB tribute/parody pieces. 4 out of 5. B
