Toothpaste

Toothpaste - such a simple thing to buy. Beijing stores have tons of different kinds of toothpaste from which to choose. I had heard that Chinese toothpaste isn't very good. It tastes terrible and lacks fluoride. So - I decided to go with a well-known brand. The first time I purchased Colgate, all was well. Tastes good; it even sparkles. So the next time I bought toothpaste, I couldn't remember the specific kind of Colgate I had bought. Each store often carries something a little different. It turns out that my previous tube was blue. What flavor could this be? It's worth a try. So - what flavor is it?
