Me waiting to catch a glimpse of the hippo, affectionately named "kaba-san" or "Mr. Hippo" in Japanese.  He is one of the star attractions at the Tobe Zoo.  The posters and pamphlets always show him opening his huge four toothed mouth in order to graciously accept carrots.  The carrots are available for purchase from a vending machine next to his tank.  I guess Mr. Hippo wasn't too hungry this afternoon...
