Dinosaur Love special: Go to Vietnam

What was the point of this special? Why did they make this special? I didn't understand it at all. What was the story line? I'm just so confused as to why the producer made this. Was it suppose to be a continuation of something? What was the issue and was it resolved? A special usually catches you up on the characters lives. I need an explanation for why this special was made. To quote CB, "WHAT WAS THE REASON??!!"

I would like to say that I love that Rak looked like an adult in the special. In Dinosaur Love he looked like a shinny 14 year old. And acted like he's was naïve and clueless. I don't understand how but it appears like he matured in the months between the series and special.
