I am looking for an animated monkey movie I watched as a kid

Hi I need to know a movie name. As Far as I remembered It was an animated monkey movie. Monkeys lived in some sort of Jungle and they had tree houses. I don't think there were people in the movie.  I think monkeys had some sort of clothes or rags on them, but I don't think they talked in human language. I think I may have watched it around 2005. It wasn't in 3d style as far as I remember. I think green and yellow were used as main colors. Some of the monkeys may have orange fur, but I am not so sure.
