TV commercial for Oishi Snack

I found a very interesting and effective advertisement for Oishi Snack, and tell you about it. First, the ad is funny. You see a group playing card game merrily, and one of them imitates a bear. But, suddenly, real bears appear, and they try to attack people. People scare them, and give Oishi Snack for bears. Second, the ad is surprising. When the bears eat an Oishi Snack, they dance cheerfully with funny music. This music reminds you this ad. Finally the ad is mysterious. The scene changes, so you can not guess what happen. However you can know it at the end of the ad, and find the products being advertised. In conclusion, the ad is effective because you keep watching it until the last, and give you an impression.
