Fantastic!

In my holiday to one Asian country, I happened to make a friendship with a local guy while I was drinking a softdrink Fanta. He speaks broken English, but I can fairly understand him. I offered him a softdrink, to that he choose Coco Cola. The guy was showing some postcard of Mountains to me. They are really beautiful and just remarked "Fantastic!". I also showed him some beautiful pictures of country side stored in my digital camera, where I have trekked. To my surprise! Can you guess what was his remark? ... ... ... ... ... ... He remarked "Coco Colastic!"
