Originally, Greg Graziani named the morph "Pastel Jungle" when he proved that the brightened look was genetic. When he proved the Cinnamon genetic, he called it "Cinnamon Pastel". This was before there were tons of morphs available. Later, there were animals called "Jungles" that have a more abberent pattern to them. Now that there are morphs like "Jungles" and Pewters (a Cinnamon crossed with a Pastel), the old names can be somewhat confusing. When someone mentions a "Pastel Jungle", though, they are talking about a Pastel (unless they specify that they are working with a line of genetic Jungles of some sort). Hopefully this clears up your confusion!
