I don't really understand why Pocky is so popular. I've been to some anime conventions, and there seems to be a frenzy over Pocky. Although it seems to have subsided a bit recently, it's still way more popular than it deserves to be. I'm pointing my finger at regular Pocky; it's mediocre at best, especially compared to other Japanese snacks (Toppo, KitKat, etc.).
However, limited edition Pocky is a different story. Although I love the mousse and dessert Pockys best, I'll try any candy or snack in a limited edition flavor. This Brazilian Pudding Pocky was given to me by my sister.
The tropical box is cute, and the stripes on the Pocky itself are quite pretty. As far as taste, it has a slight creamy caramel flavor which is pleasant, but not amazing. I'm not really sure what's Brazilian about it, but I suppose Brazilian Pudding sounds better than Exotic Purin. It just tastes like normal flan/purin to me.
Although it wasn't fantastic, it was a good light snack, and better than regular Pocky. The taste was very mild, but I suppose flan is a mild dessert, so it makes sense. This Pocky was also reviewed at Japanese Snack Food Reviews.
