i use to have one like that, it was light and dark blue swirl. It was also a double bubbler, went kinda like a W. Alas, it broke at 10K in '08 when I made the decision to try and clean it out.
cool, deffinatley looks like peppermint. I love the smallness of it. Its like the size of a spoon, but bubbly!
It works well...only complaint is that the bowl is like right underneath my nose, so I get some heat on it
